=============================================================================
SECTION 1 - GENERAL INFORMATION
1.1. What is Vim?
Vim stands for Vi IMproved. It used to be Vi IMitation, but there are so
many improvements that a name change was appropriate. Vim is a text editor
which includes almost all the commands from the Unix program "Vi" and a lot
of new ones. All commands can be given with the keyboard. This has the
advantage that you can keep your fingers on the keyboard and your eyes on
the screen. For those who want it, there is mouse support and a GUI version
with scrollbars and menus.
Vim is an editor, not a word processor. A word processor is used mainly to
do layout of text. This means positioning it, changing the way it appears
on output. More often than not, the final document is meant to be printed
or typeset or what have you, in order to present it in a pleasing manner to
others. Examples of word processors are Microsoft Word, WordPerfect,
FrameMaker, and AmiPro.
An editor is simply for entering text. Any typesetting or laying out of the
document is secondary. With an editor, one's main concern is entering text,
not making the text look good. Examples of editors other than Vim and Vi
are Emacs, Crisp, Brief, and xedit. And Notepad.
For more information, read
:help intro
1.2. Who wrote Vim?
Most of Vim was written by Bram Moolenar, with contributions from too many
people to mention here. See ":h credits" for a complete list.
Vim is based on Stevie, worked on by Tim Thompson, Tony Andrews and G.R.
(Fred) Walter.
For more information, read
:help author
1.3. Is Vim compatible with Vi?
Yes. Vim is very much compatible with Vi. You can use the "-C"
command-line flag to start Vim in Vi compatible mode:
$ vim -C
You can also use:
$ vim -u NONE
You can also set the 'compatible' option to enable Vi compatibility:
:set compatible
For more information, read
:help -C
:help 'compatible'
:help compatible-default
1.4. What are some of the improvements of Vim over Vi?
A short summary of the improvements of Vim over vi is listed below. The
list shows that Vim is a thoroughly modern and feature-packed editor.
Standard features of modern editors are implemented, and there is an equal
emphasis on general power-user features and features for programmers.
Features to modernise Vi:
Multi-level undo
Allows you to set the number of times you can undo your changes in a
file buffer. You can also redo an undone change.
Multiple windows and buffers
Each file can be displayed in its own window. You can move easily from
one window to another. Each file opened during a Vim session also has
an associated buffer and you can easily jump from one to the other.
Flexible insert mode
Vim allows you to use the arrow keys while in insert mode to move
around in the file. No more hitting <Esc>, moving around, then hitting
`i' or `a'.
Macros
Vim has a facility which allows you to record a sequence of typed
characters and repeat them any number of times.
Visual mode
You can highlight sections of text and execute operations on this
section of text only.
Block operators
Allow selection and highlighting of rectangular blocks of text in
order do execute specific operations on them.
Online help system
You can easily find help on any aspect of using Vim. Help is displayed
in its own window.
Command-line editing and history
History allows you to use the arrow keys to repeat or search for a
command that has already been typed. Allows you to match the beginning
of a command with the beginning of another similar command in the
history buffer. You can also edit a command to correct typos or change
a few values.
Command line completion.
Using the <Tab> key, you can complete commands, options, filenames,
etc. as needed.
Horizontal scrolling.
Long lines can be scrolled horizontally (with or without the GUI).
Advanced user features:
Text formatting.
With two keystrokes, you can format large sections of text, without
the use of external programs.
Word completion in Insert mode
Vim can complete words while you are typing, by matching the current
word with other similar words in the file.
Jump tags
Just like in an internet browser, you can jump back to previous parts
of the text you were editing, and then forward again. Your brain is
thus free to edit instead of navigate.
Automatic commands
Commands automatically executed when reading or writing a file,
jumping to another buffer, etc.
Viminfo
Allows storing of the command line history, marks and registers in a
file to be read on startup. Therefore, you can recall old search
patterns, macros, etc., in a new Vim session.
Mouse support
The mouse is supported in an xterm and for MS-DOS. It can be used to
position the cursor, select the visual area, paste a register, etc.
Graphical User Interface (GUI)
Just like any modern editor. Also, it's very easy to add your own
menus. Of course, console vim is still supported, and very widely
used.
Scripting language
Vim has a powerful scripting language so new commands can be created.
You can also use Perl, Python, TCL and Ruby to achieve the same thing!
Plugins
Extra functionality implemented via vim commands (regular commands or
the scripting language) that is automatically loaded on startup.
Examples: file explorer, network editing. More are being developed
and shared on VimOnline all the time.
Syntax highlighting for many programming languages
Syntax highlighting for hundreds of programming languages is
supported. Support for others can be added.
Extended regular expressions
Vim supports extended regular expressions which are similar in
functionality to that of perl regular expressions.
Programming performance features:
Edit-compile-edit speedup
You can compile within Vim and automatically jump to the location of
errors in the source code.
Indenting for many programming languages
C, C++, Java, Perl, XML and many other languages can be automatically
indented by vim while you type. Support for others can be added.
Searching for words in include files
Vim allows you to search for a match of the word under the cursor in
the current and included files.
Advance text objects
Instantly select, or delete, or copy, or indent, or format, or change
case, or ... to all the text between ( and ), or { and }, or < and >,
or [ and ]. Or a word, sentence, or paragraph. Very powerful.
Folding
Certain parts of the text can be "folded" away. The best example is
the body of a function. You can get an overview of the code, and then
open the fold of the function whose detail you need to see.
ctags and cscope integration
Using these two powerful programs, you can jump to a definition of a
function from a calling instance of it, and use other tricks to
navigate source code.
For more information, read
:help vi-differences
1.5. Is Vim free?
Vim is Charityware. There are no restrictions on using or copying Vim, but
the author encourages you to make a donation to charity. A document
explaining how to do so is included in the distribution.
For more information, read
:help copyright
=============================================================================
SECTION 2 - RESOURCES
2.1. Where can I learn more about Vim?
You can post your Vim questions to the vim@vim.org mailing list. You can
post your Vim development related questions to the vim-dev@vim.org mailing
list. Vim does not have a newsgroup of its own. But the appropriate
newsgroup to post to is comp.editors.
"VimOnline" is a web page that serves as a de facto homepage for vim,
although the main purpose of it is to gather tips and scripts from
everywhere. Get involved! The URL is vim.sourceforge.net or vim.sf.net.
Finally, read the Vi FAQ:
http://www.faqs.org/faqs/editor-faq/vi/part1/index.html
For more information, read
:help mail-list
:help internet
2.2. Is there a mailing list available?
There are several:
NAME DESCRIPTION
vim-announce Announcements of new releases
vim General discussion
vim-dev Patches, bug reports, development discussions
vim-mac Macintosh discussion
vim-fr General discussion in French
vim-multibyte Multibyte development issues
vim-vms Development on VMS
Of these, only vim and vim-dev are of general interest. vim-announce is
read-only to most people, and its messages are sent to the other lists as
well. The remaining four are very low volume.
To subscribe: send an email to <NAME>-subscribe@vim.org
To unsubscribe: send an email to <NAME>-unsubscribe@vim.org
To get help: send an email to <NAME>-help@vim.org
2.3. Is there an archive available for the Vim mailing lists?
Yes. Visit http://www.yahoogroups.com/list/<name>, where name is one of:
vimannounce, vim, vimdev, vim-fr, vim-mac, vim-multibyte, vim-vms.
Alternatively, visit www.gmane.org to find out about GMANE, which allows
you to access the mailing lists as though they were newsgroups. This
offers some convenience to those who wish to browse the history or casually
observe the current threads.
2.4. Where can I get the Vim user manual in HTML/PDF/PS format?
You can download the HTML/PDF/PS format of the Vim user manual from:
http://vimdoc.sourceforge.net/
2.5. I have a "xyz" (some) problem with Vim. How do I determine it is a
problem with my setup or with Vim?
First, you have to determine that the problem is not with your .vimrc or
.gvimrc or system vimrc or your personal plugin files or in any of your
setup files. To do this, use
$ vim -N -u NONE -U NONE
This will start Vim in 'nocompatible" mode and will not source your
personal .vimrc and .gvimrc files. It will also not load your personal
plugins. In this invocation of Vim, try to reproduce your problem. If you
are not able to reproduce the problem, then the problem is related to some
setting in one of your local setup files or plugins. To locate the problem
in your setup files, you have to use trial and error and try commenting out
the lines in your setup files one by one. You can also use the -V command
line argument to Vim to get more debug information and analyze the problem:
$ vim -V2
You can increase the value passed to the -V argument to get more debug
information.
For more information, read
:help -u
:help -U
:help -N
:help -V
:help 'verbose'
:help :verbose
:help set-verbose
2.6. Where can I report bugs?
First collect the required information using the following command:
:source $VIMRUNTIME/bugreport.vim
Now send the resulting text from the above command to the bugs@vim.org
e-mail address.
The Vim Development mailing list (see above) is a good place to discuss
general bugs. If the bug you find is with syntax highlighting or some
other "added feature" (i.e. not directly programmed into vim), attempt to
inform the maintainer of that feature.
For more information, read
:help bug-reports
2.7. Where can the FAQ be found?
The FAQ can be found at VimOnline (vim.sf.net). Other places will be
decided in the future.
2.8. What if I don't find an answer in this FAQ?
This FAQ covers mainly Vim-specific questions. You may find more
information suitable for most Vi clones by reading the Vi FAQ. It is posted
regularly on comp.editors. You can also find a copy at
http://www.faqs.org/faqs/editor-faq/vi/part1/index.html
Also, since Vim has gathered so many features in the last few years,
successfully documenting the frequently asked questions here is a
near-impossible task. To make it possible, please email the maintainer if
you have a good question. A good question is one that you've tried to
answer yourself (remember, Vim has great documentation) but struggled.
2.9. I have a patch for implementing a Vim feature. Where can I send this
patch?
You can send your patches to the Vim developer mailing list
vim-dev@vim.org.
For more information, read
:help vim-dev
2.10. I have a Vim tip or developed a new Vim
syntax/indent/filetype/compiler plugin or developed a new script or a
colorscheme. Is there a public website where I can upload this?
Yes. You can use the Vim Online website to upload your plugins/scripts,
colorschemes, tips, etc. The site is at http://vim.sourceforge.net

=============================================================================
SECTION 4 - HELP
4.1. How do I use the help files?
Help can be found for all functions of Vim. In order to use it, use the
":help" command. This will bring you to the main help page. On that first
page, you will find explanations on how to move around. Basically, you move
around in the help pages the same way you would in a read-only document.
You can jump to specific subjects by using tags. This can be done in two
ways:
* Use the "<Ctrl-]>" command while standing on the name of a command or
option. This only works when the tag is a keyword. "<Ctrl-LeftMouse>"
and "g<LeftMouse>" work just like "<Ctrl-]>".
* use the ":tag <subject>" command. This works with all characters.
Use "<Ctrl-T>" to jump back to previous positions in the help files. Use
":q" to close the help window.
If you want to jump to a specific subject on the help pages, use ":help
{subject}". If you don't know what to look for, try ":help index" to get a
list of all available subjects. Use the standard search keys to locate the
information you want. You can abbreviate the ":help" command as ":h".
For more information, read
:help online-help
4.2. How do I search for a keyword in the Vim help files?
You can press the CTRL-D key after typing the help keyword to get a list of
all the help keywords containing the supplied pattern. You can also use the
meta characters like *, \+, etc to specify the help search pattern:
:help init<C-D>
:help str*()<C-D>
:help '*indent<C-D>
You can press the Tab key after typing a partial help keyword to expand to
the matching keyword. You can continue to press the Tab key to see other
keyword matches.
From the help window, you can use the ":tag" command to search for
keywords. For example,
:tselect /window
This command will list all the help keywords containing the text "window".
You can select one from the list and jump to it.
You can use the ":helpgrep" command to search for the given text in all the
help files. The quickfix window will be opened with all the matching lines.
For more information, read
:help c_CTRL-D
:help c_<Tab>
:help :tselect
:help :help
:help :helpgrep
4.3. I am getting an error message E123, what did I do wrong?
You can get more information about the error and the error message using:
:help E123
For more information, read
:help error-messages
4.4. Where can I read about the various modes in Vim?
You can get information about the different modes in Vim by reading
:help vim-modes
4.5. How do I generate the Vim help tags file after adding a new Vim help
file?
You can use the ":helptags" command to regenerate the Vim help tag file.
For example:
:cd $VIMRUNTIME/doc
:helptags .
For more information, read
:help :helptags
:help add-local-help
4.6. Can I use compressed versions of the help files?
Yes. You can compress the help files and still be able to view them with
Vim. This makes accessing the help files a bit slower and requires the
"gzip" utility. Follow these steps to compress and use the Vim help files:
- Compress all the help files using "ggzip doc/*.txt".
- Edit the "doc/tags" file and change the ".txt" to ".txt.gz" using
:%s=\(\t.*\.txt\)\t=\1.gz\t=
- Add the following line to your vimrcc:
set helpfile={dirname}/help.txt.gz
Where {dirname} is the directory where the help files are. The gzip.vim
plugin supplied with the standard Vim distribution will take care of
decompressing the files. You must make sure that $VIMRUNTIME is set to
where the other Vim files are, when they are not in the same location as
the compressed "doc" directory.
For more information, read
:help gzip-helpfile
:help 'helpfile'
:help gzip
:help $VIMRUNTIME
=============================================================================
SECTION 5 - EDITING A FILE
5.1. I am currently editing a file in Vim. How do I load another file into
Vim?
There are several ways to load another file for editing. The simplest is to
use the ":e" command:
:e <another file>
For more information, read
:help usr_07
:help edit-files
5.2. How do I save the current file in another name (save as) and edit a
new file?
You can use the ":saveas" command to save the current file in another name:
:saveas <newfilename>
Alternatively, you can also do:
:w <newfilename>
:edit #
You can also use the ":file" command, followed by ":w" command:
:file <newfilename>
:w
For more information, read
:help :saveas
:help :file_f
:help :w
5.3. How do I change the current directory to the directory of the current
file?
You can use the following command to change the current directory to the
directory of the current file:
:cd %:p:h
To automatically change the current directory to the directory of the
current file, use the following autocmd:
:autocmd BufEnter * cd %:p:h
For more information, read
:help :cd
:help :lcd
:help filename-modifiers
:help autocommand
5.4. How do I write a file without the line feed (EOL) at the end of the
file?
You can turn off the 'eol' option and turn on the 'binary' option to write
a file without the EOL at the end of the file:
:set binary
:set noeol
:w
For more information, read
:help 'endofline'
:help 'binary'
:help 23.4
5.5. How do I configure Vim to open a file at the last edited location?
Vim stores the cursor position of the last edited location for each buffer
in the '"' register. You can use the following autocmd in your .vimrc or
.gvimrc file to open a file at the last edited location:

SECTION 6 - EDITING MULTIPLE FILES
6.1. How do I switch between files while editing multiple files in Vim?
There are several ways to switch between multiple files. You can use the
":buffer" command to switch between multiple files. For example,
:buffer file1
:buffer file2
You can also use the CTRL-^ key to switch between buffers. By specifying a
count before pressing the key, you can edit the buffer with that number.
Without the count, you can edit the alternate buffer by pressing CTRL-^
You can also use the ":e #" command to edit a particular buffer:
:e #5

6.2. How do I configure Vim to autoload several files at once similar to
"work-sets" or "projects"?
You can use the ":mksession" and ":mkview" commands to achieve this. The
mksession command creates a Vim script that restores the current editing
session. You can use the ":source" command to source the file produced by
the mksession command. The mkview command creates a Vim script that
restores the contents of the current window. You can use the ":loadview"
command to load the view for the current file.

horizontally or vertically split windows. For example:
$ vim -o2
$ vim -O2
For more information, read
:help -o
:help -O
:help startup-options
6.6. How do I browse/explore directories from within Vim?
You can use the explorer.vim plugin, supplied with the standard Vim
package, to browse/explore directories from within Vim. You can start the
file explorer using one of the following commands:
:e <directory>
:Explore
:SExplore
From the file explorer, you can browse through directories, rename, delete
and edit files.
For more information, read

6.7. How do I edit files over a network using ftp/scp/rcp/http?
You can use the netrw.vim plugin, supplied with the standard Vim package,
to edit files over a network using ftp/scp/rcp/http. Using this plugin, Vim
will transparently load and save the files over ftp/scp/rcp/http. For
example, to edit a file over ftp, you can use the following command:
$ vim ftp://machine/path
For more information, read
:help netrw.vim
=============================================================================
SECTION 7 - BACKUP
7.1. When I edit and save files, Vim creates a file with the same name as
the original file and a "~" character at the end. How do I stop Vim
from creating this file? (or) How do I disable the Vim backup file
feature?
You have set the 'backup' option, so Vim creates a backup file when saving
the original file. You can stop Vim from creating the backup file, by
clearing the option:
:set nobackup
Note that, by default this option is turned off. You have explicitly
enabled the 'backup' option in one of the initialization files. You may
also have to turn off the 'writebackup' option:
:set nowritebackup
For more information, read
:help 07.4
:help backup-table
:help 'backup'
:help 'writebackup'
:help 'backupskip'
:help 'backupdir'
:help 'backupext'
:help 'backupcopy'
:help backup
7.2. How do I configure Vim to store all the backup files in a particular
directory?
You can configure Vim to store all the backup files in a particular
directory using the 'backupdir' option. For example, to store all the
backup files in the ~/backup directory, you can use the following command:
:set backupdir=~/backup
For more information, read
:help 07.4
:help 'backupdir'
:help backup
7.3. When I save a file with Vim, the file permissions are changed.
How do I configure Vim to save a file without changing the file
permissions?
This may happen, if the 'backupcopy' option is set to 'no' or 'auto'. Note
that the default value for this option is set in such a way that this will
correctly work in most of the cases. If the default doesn't work for you,
try setting the 'backupcopy' option to 'yes' to keep the file permission
when saving a file:
:set backupcopy=yes
This applies, only if you have configured Vim to make a backup whenever
overwriting a file. By default, Vim will not backup files.
For more information, read
:help 'backupcopy'
:help backup
:help 'backup'
:help 'writebackup'
=============================================================================
SECTION 8 - BUFFERS
8.1. I have made some modifications to a buffer. How do I edit another
buffer without saving the modified buffer and also without losing the
modifications?
You can set the 'hidden' option to edit a file without losing modifications
to the current file:
:set hidden
By setting the 'hidden' option, you can also save the modification history
(undo-history) for the buffer. Otherwise, as you switch between files, the
undo-history will be lost.
For more information, read
:help 'hidden'
:help hidden-quit
:help :hide
8.2. How do I configure Vim to auto-save a modified buffer when switching
to another buffer?
You can set the 'autowrite' option to auto-save a modified buffer when
switching to another buffer:
:set autowrite
For more information, read
:help 'autowrite'
:help 'autowriteall'
:help 'hidden'
8.3. How do I replace the buffer in the current window with a blank buffer?
You can use the ":enew" command to load an empty buffer in place of the
buffer in the current window.
For more information, read
:help :enew
8.4. Is there a keyboard shortcut to load a buffer by the buffer number?
You can use the CTRL-^ command to load a buffer by specifying the buffer
number. For example, to load buffer number 5, you have to use the 5 CTRL-^
command.
For more information, read
:help CTRL-^
8.5. How do I open all the current buffers in separate windows?
You can use the ":ball" or ":sball" commands to open all the buffers
in the buffer list:
:ball
For more information, read
:help :ball
8.6. How do I close (delete) a buffer without exiting Vim?
You can use the ":bdelete" command to delete a buffer without exiting Vim.
For example:
:bdelete file1
For more information, read

8.7. I have several buffers opened with :e filename. How do I close one of
the buffers without exiting Vim?
You can use the ":bdelete <buffername>" command to close the buffer.
For more information, read
:help :bdelelete
:help :bunload
:help :bwipeout
8.8. When I use the command ":%bd" to delete all the buffers, not all the
buffers are deleted. Why?
In the ":%bd" command, the '%' range will be replaced with the starting and
ending line numbers in the current buffer. Instead of using '%' as the
range, you should specify numbers for the range. For example, to delete all
the buffers, you can use the command ":1,9999bd".
For more information, read
:help :bd
8.9. How do I display the buffer number of the current buffer/file?
You can use 2<CTRL-G> command to display the buffer number for the current
file/buffer. Note the use of count before the CTRL-G command. If the count
is greater than 1, then Vim will display the buffer number.
You can also use the following command to display the current buffer
number:
:echo bufnr("%")
You can also include the "%n" field to the 'statusline' option to display
the current buffer number on the statusline.
For more information read,
:help CTRL-G
:help bufnr()
:help :echo
:help 'statusline'
8.10. How do I delete a buffer without closing the window in which the
buffer is displayed?
You can use the following command to open the next buffer and delete
the current buffer.
:bnext | bdelete #
For more information read,

:nnoremap <S-C-Tab> :bprevious<CR>
For more information read,
:help :bnext
:help :previous
=============================================================================
SECTION 9 - WINDOWS
9.1. What is the difference between a Vim window and a buffer?
A Vim buffer is a file loaded into memory for editing. The original file
remains unchanged until you write the buffer to the file. A Vim window is a
viewport onto a buffer. You can use multiple windows on one buffer or
several windows on different buffers.
For more information, read
:help usr_08.txt
:help 22.4
:help windows-intro
:help Q_wi
9.2. How do I increase the width of a Vim window?
You can increase the width of a Vim window using one of the following
commands:
:vert resize +N
:vert resize -N
:vert resize N
You can also use CTRL-W < or CTRL-W > or CTRL-W | commands.
For more information, read
:help vertical-resize
:help CTRL-W_
:help CTRL-W_<
:help window-resize
9.3. How do I zoom into or out of a window?
You can zoom into a window (close all the windows except the current
window) using the "CTRL-W o" command or the ":only" ex command.
You can use the "CTRL-W _" command or the ":resize" ex command to increase
the current window height to the highest possible without closing other
windows.
You can use the "CTRL-W |" command or the ":vertical resize" ex command to
increase the current window width to the highest possible without closing
other windows.
You can use the "CTRL-W =" command to make the height and width of all the
windows equal.
You can also set the following options to get better results with the above
commands:
Method 1:
Set the 'winminheight' option to 0:
:set winminheight=0
By default, this option is set to 1.
This option controls the minimum height of an inactive window (when it is
not the current window). When the 'winminheight' option is set to 0, only
the status line will be displayed for inactive windows.
Method 2:
Set the 'noequalalways' option and set the 'winheight' option to a large
value (like 99999):
:set noequalalways
:set winheight=99999
Now, the active window will always open to its maximum size, while the
other windows will stay present, but shrunken to just a status line.
With any of the above mentioned methods, you cannot restore the window
layout after zooming into a window. If you want to restore the Vim window
layout after zooming into a window, you can use the ZoomWin plugin. You can
download this plugin from the Vim online website at:
http://vim.sourceforge.net/scripts/script.php?script_id=508

9.4. How do I execute an ex command on all the open buffers or open windows
or all the files in the argument list?
You can use the ":bufdo" command to execute an ex command on all the open
buffers. You can use the ":windo" command to execute an ex command on all
the open windows. You can use the ":argdo" command to execute an ex
command on all the files specified in the argument list.

=============================================================================
SECTION 10 - MOTION
10.1. How do I jump to the beginning (first line) or end (last line) of a
file?
You can use 'G' command to jump to the last line in the file and the 'gg'
command to jump to the first line in the file.
For more information, read
:help G
:help gg
10.2. In insert mode, when I press the <Esc> key to go to command mode, the
cursor moves one character to the left (except when the cursor is on
the first character of the line). Is it possible to change this
behavior to keep the cursor at the same column?
No. It is not possible to change this behavior. The cursor is *always*
positioned on a valid character (unless you have virtual-edit mode
enabled). So, if you are appending text to the end of a line, when you
return to command mode the cursor *must* drop back onto the last character
you typed. For consistency sake, the cursor drops back everywhere, even if
you are in the middle of a line.
You can use the CTRL-O command in insert mode to execute a single ex
command and return back to insert mode without moving the cursor column.
For more information, read
:help 'virtual'
:help i_CTRL-O
10.3. How do I configure Vim to maintain the horizontal cursor position when
scrolling with the <Page Up>, <Page Down>, etc keys?
You can reset the 'startofline' option to keep the cursor at the same
horizontal location when scrolling text:
:set nostartofline
For more information, read
:help 'startofline'
10.4. Some lines in a file are more than the screen width and they are all
wrapped. When I use the j, k keys to move from one line to the next,
the cursor is moved to the next line in the file instead of the next
line on the screen. How do I move from one screen line to the next?
You can use the gj and gk commands to move from one screen line to the
next/previous screen line. The j and k commands move the cursor from one
file line to the next file line. You can also avoid the line wrapping by
resetting the 'wrap' option:
:set nowrap
For more information, read
:help gj
:help gk
:help 'wrap'
You can use the following mappings:
:map <Up> gk
:imap <Up> <C-o>gk
:map <Down> gj
:imap <Down> <C-o>gj
10.5. What is the definition of a sentence, paragraph and section in Vim?
A sentence is defined as ending at a '.', '!' or '?' followed by either the
end of a line, or by a space (or two) or tab. Which characters and the
number of spaces needed to constitute a sentence ending is determined by
the 'joinspaces' and 'cpoptions' options.
A paragraph begins after each empty line, and also at each of a set of
paragraph macros, specified by the pairs of characters in the 'paragraphs'
option.
A section begins after a form-feed (<C-L>) in the first column and at each
of a set of section macros, specified by the pairs of characters in the
'sections' option.
For more information, read
:help sentence
:help 'joinspaces'
:help 'cpoptions' | /^\s*j\
:help paragraph
:help section
:help word
10.6. How do I jump to beginning or end of a sentence, paragraph or a
section?
You can use the following motion commands to jump to the beginning or end
of a sentence or a paragraph or a section:
motion position where
( beginning current sentence
) end current sentence
{ beginning current paragraph
} end current paragraph
[] end previous section
[[ beginning current section
][ end current section
]] beginning next section
Each of these motions can be preceded by a number which will extend the
jump forward (or backward).
For more information, read
:help object-motions
10.7. I have lines in a file that extends beyond the right extent of the
screen. How do I move the Vim view to the right to see the text off
the screen?
You can use one of the following commands to horizontally scroll the screen
to the left or right:
zl - scroll to the left
zh - scroll to the right
zL - scroll half a screenwidth to the left
zH - scroll half a screenwidth to the right
zs - scroll to position the cursor at the start of the screen
ze - scroll to position the cursor at the end of the screen
You can use the g0 command to move the cursor to the first character of the
screen line and the g$ command to move the cursor to the last character of
the screen line without scrolling the screen.
For more information, read
:help scroll-horizontal
10.8. How do I scroll two or more buffers simultaneously?
You can set the "scrollbind" option for each of the buffer to scroll them
simultaneously.
For more information, read
:help 'scrollbind'
:help scroll-binding
:help 'scrollopt'
10.9. When I use my arrow keys, Vim changes modes, inserts weird characters
in my document but doesn't move the cursor properly. What's going on?
There are a couple of things that could be going on: either you are using
Vim over a slow connection or Vim doesn't understand the key sequence that
your keyboard is generating.
If you are working over a slow connection (such as a 2400 bps modem), you
can try to set the 'timeout' or 'ttimeout' option. These options, combined
with the 'timeoutlen' and 'ttimeoutlen' options, may fix the problem.
The preceding procedure will not work correctly if your terminal sends key
codes that Vim does not understand. In this situation, your best option is
to map your key sequence to a matching cursor movement command and save
these mappings in a file. You can then ":source" the file whenever you work
from that terminal.
For more information, read
:help 'timeout'
:help 'ttimeout'
:help 'timeoutlen'
:help 'ttimeoutlen'
:help :map
:help vt100-cursor-keys
10.10. How do I configure Vim to move the cursor to the end of the previous
line, when the left arrow key is pressed and the cursor is currently
at the beginning of a line?
You can add the '<' flag to the 'whichwrap' option to configure Vim to move
the cursor to the end of the previous line, when the left arrow key is
pressed and the cursor is currently at the beginning of a line:
:set whichwrap+=<
Similarly, to move the cursor the beginning of the next line, when the
right arrow key is pressed and the cursor is currently at the end of a
line, add the '>' flag to the 'whichwrap' option:
:set whichwrap+=
The above will work only in normal and visual modes. To use this in insert
and replace modes, add the '[' and ']' flags respectively.
For more information, read
:help 'whichwrap'
:help 05.7
10.11. How do I configure Vim to stay only in insert mode (modeless
editing)?
You can set the 'insertmode' option to configure Vim to stay only in insert
mode:
:set insertmode
By setting this option, you can use Vim as a modeless editor. If you press
the <Esc> key, Vim will not go to the normal mode. To execute a single
normal mode command, you can press CTRL-O followed by the normal mode
command. To execute more than one normal command, you can use CTRL-L
followed by the commands. To return to insert mode, press the <Esc> key. To
disable this option, reset the 'insertmode' option:
:set noinsertmode
You can also start vim using the "evim" command or you can use "vim -y" to
use Vim as a modeless editor.

lines (context) above and below the cursor.
:set scrolloff=10
For more information, read
:help 'scrolloff'
:help 'sidescrolloff'
10.13. How do I go back to previous cursor locations?
You can go back to the cursor location before the latest jump using the ''
or `` command. You can use the CTRL-O command to go back to older cursor
positions and the CTRL-I command to go to the newer cursor positions in the
jump list.

SECTION 11 - SEARCHING TEXT
11.1. After I searched for a text with a pattern, all the matched text
stays highlighted. How do I turn off the highlighting
temporarily/permanently?
The 'hlsearch' option controls whether all the matches for the last
searched pattern are highlighted or not. By default, this option is not
enabled. If this option is set in a system-wide vimrc file, then you can
turn off the search highlighting by using the following command:
:set nohlsearch
To temporarily turn off the search highlighting, use
:nohlsearch
You can also clear the search highlighting, by searching for a pattern that
is not in the current file (for example, search for the pattern 'asdf').

- If all the lines end with carriage rreturn (<CR>), then the fileformat is
'mac'.
If the file has some lines ending with <CR> and some lines ending with <CR>
followed by a <NL>, then the fileformat is set to 'unix'.
You can change the format of the current file, by modifying the
'fileformat' option and then saving the file:
:set fileformat=dos
:w
To display the format of the current file, use
:set fileformat?
The above behavior is also controlled by the 'fileformats' option. You can
try the following commands:
:set fileformats+=unix
:e <your_file>
:set fileformat=unix

14.14. When I paste some text into a Vim buffer from another application,
the alignment (indentation) of the new text is messed up. How do I
fix this?
The indentation of the text is messed up due to various Vim settings
related to indentation (like autoindent, smartindent, textwidth etc).
Before pasting text into Vim, you can set the 'paste' option:
:set paste
After pasting the text, you can turn off the option using:
:set nopaste
You can also toggle the paste option using:
:set paste!
If you can access the clipboard through the * register, then you can paste
the text without indentation using CTRL-R CTRL-O *.

14.15. When there is a very long wrapped line (wrap is "on") and a line
doesn't fit entirely on the screen it is not displayed at all. There
are blank lines beginning with '@' symbol instead of wrapped line. If
I scroll the screen to fit the line the '@' symbols disappear and the
line is displayed again. What Vim setting control this behavior?
You can set the 'display' option to 'lastline' to display as much as
possible of the last line in a window instead of displaying the '@'
symbols.
:set display=lastline
For more information, read
:help 'display'
14.16. How do I convert all the tab characters in a file to space
characters?
You can use the ":retab" command to update all the tab characters in the

SECTION 15 - VISUAL MODE
15.1. How do I do rectangular block copying?
You can do rectangular block copying in Vim using the blockwise visual
mode. To start blockwise visual mode use the CTRL-V key. Move the cursor
using any of the motion commands and then use the y operator to yank to
visually selected text.
If CTRL-V does not work as expected, it may have been remapped to CTRL-Q by
the mswin.vim script which is often sourced by a vimrc on Windows machines
to mimic some common short cuts from other programs.
For more information, read
:help 04.4
:help blockwise-visual
:help visual-mode
:help Q_vi
15.2. How do I delete or change a column of text in a file?
You can use the Vim block-wise visual mode to select the column of text and
apply an operator (delete, change, copy, etc) on it.
For more information, read
:help visual-block
:help visual-operators
15.3. How do I apply an ex-command on a set of visually selected lines?
When you select a range of lines in visual mode, the < register is set to
the start of the visual region and the > register is set to the end of the
visual region. You can use these registers to specify the range for an ex
command. After visually selecting the lines, press ":" to go to the command
mode. Vim will automatically insert the visual range '<,'>. You can run
any ex-command on the visual range.
For more information, read
:help v_:
:help '<
:help '
15.4. How do I execute an ex command on a column of text selected in Visual
block mode?
All the ex commands operate on whole lines only. If you try to execute an
ex command on a column of text selected in visual block mode, Vim will
operate on all the selected lines (instead of the selected columns). You
can use the vis.vim plugin script from http://vim.sourceforge.net scripts
archive to do this.
For more information, read
:help cmdline-ranges
:help 10.3
:help cmdline-lines
15.5. How do I select the entire file in visual mode?
You can select the entire file in visual mode using ggVG.
gg - go to the beginning of the file.
V - Start linewise visual mode
G - goto the end of the file.
For more information, read
:help gg
:help linewise-visual
:help G
15.6. When I visually select a set of lines and press the > key to indent
the selected lines, the visual mode ends. How can I reselect the
region for further operation? (or) How do I re-select the last
selected visual area again?
You can use the 'gv' command to reselect the last selected visual area. You
can also use the marks '< and '> to jump to the beginning or the end of the
last selected visual area.
For more information, read
:help gv
:help '<
:help '
15.7. How do I jump to the beginning/end of a visually selected region?
You can use the 'o' command to jump to the beginning/end of a visually
selected region.
For more information, read
:help v_o
15.8. When I select text with mouse and then press : to enter an ex
command, the selected text is replaced with the : character. How do I
execute an ex command on a text selected using the mouse similar to
the text selected using the visual mode?
This will happen if you have configured Vim to use select mode instead of
Visual mode by setting the 'selectmode' option. Check the value of this
option:
:set selectmode?
This mode is known as selectmode and is similar to the visual mode. This
option is also automatically set when you use the "behave mswin" command.
Select mode looks like visual mode, but it is similar to the selection mode
in MS-Windows.
For more information, read
:help Select-mode
:help 'selectmode'
:help 9.4
:help :behave
15.9. When I select a block of text using the mouse, Vim goes into
selection mode instead of Visual mode. Why?
The 'selectmode' option controls whether Select mode will be started when
selecting a block of text using the mouse. To start Visual mode when
selecting text using mouse, remove the 'mouse' value from the 'selectmode'
option:
:set selectmode-=mouse
Note that by default, the 'selectmode' option will be set to empty, so that
always visual mode is used.
For more information, read
:help 'selectmode'
:help Select-mode
:help :behave
15.10. How do I visually select the last copy/pasted text?
You can use the '[ and '] marks to visually select the last copy/pasted
text. The '[ mark is set to the beginning of the last changed/yanked text
and the '] mark is set to the end of the last changed/yanked text. To
visually select this block of text use the command '[v']

=============================================================================
SECTION 16 - COMMAND-LINE MODE
16.1. How do I use the name of the current file in the command mode or an
ex command line?
In the command line, the '%' character represents the name of the current
file. In some commands, you have to use expand("%") to get the filename:
:!perl %
For more information, read
:help :_%
:help cmdline-special
:help expand()
16.2. How do I edit the text in the Vim command-line effectively?
You can use the command-line window for editing Vim command-line text. To
open the Vim command-line window use the "q:" command in normal mode. In
command-line mode, use the CTRL-F key. In this window, the command line
history will be displayed. You can use normal Vim keys/commands to edit any
previous/new command line. To execute a command line, press the
enter/return key.
In a similar vain, the search history can be edited with "q/" and "q?"
commands.
For more information, read
:help cmdline-window
16.3. How do I switch from Vi mode to Ex mode?
You can use the Q command to switch from Vi mode to Ex mode. To switch from
Ex mode back to the Vi mode, use the :vi command.
For more information, read
:help Q
:help gQ
:help Ex-mode
:help :vi
16.4. How do I copy the output from an ex-command into a buffer?
To copy the output from an ex-command into a buffer, you have to first get
the command output into a register. You can use the ":redir" command to get
the output into a register. For example,
:redir @a
:g/HelloWord/p
:redir END
Now the register 'a' will contain the output from the ex command
"g/HelloWord/p". Now you can paste the contents of the register 'a' into a
buffer. You can also send or append the output of an ex-command into a file
using the 'redir' command.
You can prefix the ":global" command with ":silent", to avoid having the
lines printed to the screen.
To redirect the output from an ex-command to a file, you can use the
following set of commands:
:redir > myfile
:g/HelloWord/p
:redir END
For more information, read
:help :redir
:help :silent
16.5. When I press the tab key to complete the name of a file in the
command mode, if there are more than one matching file names, then
Vim completes the first matching file name and displays a list of all
matching filenames. How do I configure Vim to only display the list
of all the matching filenames and not complete the first one?
You can modify the 'wildmode' option to configure the way Vim completes
filenames in the command mode. In this case, you can set the 'wildmode'
option to 'list':
:set wildmode=list
For more information, read
:help 'wildmode'
16.6. How do I copy text from a buffer to the command line and from the
command line to a buffer?
To copy text from a buffer to the command line, after yanking the text from
the buffer, use Ctrl-R 0 in the command line to paste the text. You can
also yank the text to a specific register and use CTRL-R <register> to
paste the text to the command line. You can use CTRL-R CTRL-W to paste the
word under the cursor in the command line.
To copy text from the command line into a buffer, you can paste the
contents of the : register using the ":p command. The most recently
executed command line is stored in the : register.
Another approach for copying and pasting text to and from the command line
is to open the command line window using q: from normal mode or CTRL-F from
the command-line mode. In the command line window you can use all the Vim
commands to edit the command line.
For more information, read
:help c_CTRL-R
:help quote_:
:help cmdline-window
16.7. How do I put a command onto the command history without executing it?
To put a command onto the command history without executing it, press the
<Esc> key to cancel the command.
For more information, read

enabled by a system-wide vimrc file, then you can disable the viminfo
feature by setting the 'viminfo' option to an empty string in your local
.vimrc file:
:set viminfo=""
For more information, read
:help 'viminfo'
17.3. How do I save and use Vim marks across Vim sessions?
You can save and restore Vim marks across Vim sessions using the viminfo
file. To use the viminfo file, make sure the 'viminfo' option is not empty.
To save and restore Vim marks, the 'viminfo' option should not contain the
'f' flag or should have a value greater than zero for the 'f' option.

19.3. How do I set an option that affects only the current buffer/window?
You can use the ":setlocal" command to set an option that will affect only
the current file/buffer:
:setlocal textwidth=70
Note that not all options can have a local value. You can use ":setlocal"
command to set an option locally to a buffer/window only if the option is
allowed to have a local value.
You can also use the following command to set a option locally:
:let &l:{option-name} = <value>
For more information, read
:help :setlocal
:help local-options
19.4. How do I use space characters for a Vim option value?
To use space characters in a Vim option value, you have to escape the space
character. For example:
:set tags=tags\ /usr/tags
For more information, read
:help option-backslash
19.5. Can I add (embed) Vim option settings to the contents of a file?
You can use modelines to add Vim option settings to the contents of a file.
For example, in a C file, you can add the following line to the top or the
bottom of the file:
/* vim:sw=4: */
This will set the 'shiftwidth' option to 4, when editing that C file.
For this to work, the 'modeline' option should be set. By default, the
'modeline' option is set. The 'modelines' settings specifies the number of
lines that will be checked for the Vim set commands.

19.6. How do I display the line numbers of all the lines in a file?
You can set the 'number' option to display the line numbers for all the
lines.
:set number
For more information, read
:help 'number'
19.7. How do I change the width of the line numbers displayed using the
"number" option?
The width used for displaying the line numbers for the 'number' option is
hard-coded in Vim. It is not possible to change this width by setting some
option.
The request and the patch to add an option to change the number of columns
used for the 'number' option is in the Vim todo list:
"Add an option to set the width of the 'number' column. Eight
positions is often more than needed. Or adjust the width to the length
of the file?
Add patch that adds 'numberlen' option. (James Harvey)
Other patch with min and max from Emmanuel Renieris (2002 Jul 24)
Other patch without an option by Gilles Roy (2002 Jul 25)"
19.8. How do I display (view) all the invisible characters in a file?
You can set the 'list' option to see all the invisible characters in your
file.
:set list
With this option set, you can view space characters, tabs, newlines,
trailing space characters and wrapped lines.
You can modify the 'listchars' option to configure how the invisible
characters are displayed. For example, with the following command all the
trailing space characters will be displayed with a '.' character.
:set listchars=trail:.
For more information, read
:help 'listchars'
:help 'list'
19.9. How do I configure Vim to always display the current line and column

:help initialization
19.15. Why do I hear a beep (why does my window flash) about 1 second after
I hit the Escape key?
This is normal behavior. If your window flashes, then you've got the visual
bell on. Otherwise, you should hear a beep.
Vim needs a timeout to tell the difference between a simple escape and,
say, a cursor key sequence. When you press a key in normal mode (and even
in insert mode) and that key is the beginning of a mapping, Vim waits a
certain amount of time to see if the rest of the mapping sequence follows.
If the mapping sequence is completed before a given timeout period, the
mapping for that sequence of keys is applied. If you interrupt the mapping,
the normal actions associated with the keys are executed.
For example, if you have a mapping defined as ":imap vvv Vim is great!!"
and you type "vvv" quickly, the "Vim is great!!" will be inserted into your
text. But if you type "vv v" then that is what will put into your text.
This is also true if you type "vvv" too slowly where "too slowly" is longer
than the value for the timeout option. Setting the timeout option to a
larger value can help alleviate problems that appear when using function
keys over a slow line.
For more information, read
:help ttimeout
19.16. How do I make the 'c' and 's' commands display a '$' instead of
deleting the characters I'm changing?
To make the 'c' and 's' commands display a '$' instead of deleting the
characters, add the $ flag to the 'cpoptions' option:
:set cpoptions+=$
For more information, read
:help 'cpoptions'
19.17. How do I remove more than one flag using a single ":set" command
from a Vim option?
You can remove more than one flag from a Vim option using a single ":set"
command, by specifying the flags in exactly the same order as they appear
in the option. For example, if you use the following command to remove the
't' and 'n' flags from the 'formatoptions' option:
:set formatoptions-=tn
The 't' and 'n' flags will be removed from the 'formatoptions' option, only
if the 'formatoptions' option contains these flags in this order: 'tn'.
Otherwise, it will not remove the flags. To avoid this problem, you can
remove the flags one by one:
:set formatoptions-=t formatoptions-=n
For more information, read
:help :set-=
=============================================================================
SECTION 20 - MAPPING KEYS
20.1. How do I know what a key is mapped to?
To see what a key is mapped to, use the following commands:
:map <key>
:map! <key>
You can also check the mappings in a particular mode using one of the
":cmap", ":nmap", ":vmap", ":imap", ":omap", etc commands.
For more information, read
:help map-listing
:help map-overview
20.2. How do list all the user-defined key mappings?
You can list all the user-defined key mappings using:
:map
For more information, read
:help map-listing
20.3. How do I unmap a previously mapped key?
You can unmap a previously mapped key using the ":unmap" command:
:unmap <key>
:unmap! <key>
For mode specific mappings, you can use one of the
":nunmap/:vunmap/:ounmap/:iunmap/:lunmap/:cunmap" commands.
The following command will fail to unmap a buffer-local mapped key:
:unmap <key>
To unmap a buffer-local mapped key, you have to use the <buffer> keyword in
the unmap command:
:unmap <buffer> <key>
:unmap! <buffer> <key>
For more information, read
:help :unmap
:help map-modes
:help map-local
:help 'mapleader'
20.4. I am not able to create a mapping for the <xxx> key. What is wrong?
First make sure that the key is passed to Vim. In insert mode, press CTRL-V
followed by the desired key. You should see the keycode corresponding to
the key . If you do see the keycode, then you can create a mapping for the
key using the following command:
:map <C-V><xxx> <your_command_to_be_mapped>
For more information, read
:help map-keys-fails
:help :map-special-keys
:help key-codes
20.5. How do I map the numeric keypad keys?
First make sure that the numeric keypad keys are passed to Vim. Next, you
can use the following command to map the numeric keypad keys:
:map <kSomething> <your_command>
where, <kSomething> can be kHome, kEnd, kPageUp, kPageDown, kPlus, kMinus,
kDivide, kMultiply, kEnter, etc.
For more information, read
:help key-codes
:help terminal-options
20.6. How do I create a mapping that works only in visual mode?
You can create mappings that work only in specific mode (normal, command,
insert, visual, etc). To create a mapping that works only in the visual
mode, use the ":vmap" command:
:vmap <F3> <your mapping here>
For more information, read
:help :vmap
:help map-modes
:help 40.1
20.7. In a Vim script, how do I know which keys to use for my mappings, so
that the mapped key will not collide with an already used key?
Vim uses most of the keys in the keyboard. You can use the <leader> prefix
in maps to define keys which will not overlap with Vim keys. For example:
:map <leader>S <C-W>s
:map <leader>j <C-W>j
:map <leader>k <C-W>k
where by default <leader> gets substituted with a backslash (\), so the
user would enter
\s
\j
\k
to invoke the above map commands. The user can change the mapleader
variable to be whatever they wanted:
:let mapleader = ","
When writing a plugin or other script, more often than not, it is advisable
to use :noremap instead of :map to avoid side effects from user defined
mappings.
For more information, read
:help <Leader>
:help <LocalLeader>
:help write-plugin
20.8. How do I map the escape key?
You can map the Escape key to some other key using the ":map" command. For
example, the following command maps the escape key to CTRL-O.
:map <C-O> <Esc>
20.9. How do I map a key to perform nothing?
You can map a key to <Nop> to perform nothing when the key is pressed. For
example, with the following mappings, the <F7> key will do nothing when
pressed.
:map <F7> <Nop>
:map! <F7> <Nop>
For more information, read
:help <Nop>
:help :map
:help :map!
:help map-modes
20.10. I want to use the Tab key to indent a block of text and Shift-Tab
key to unindent a block of text. How do I map the keys to do this?
This behavior is similar to textpad, visual studio, etc.
Use the following mapping:
:inoremap <S-Tab> <C-O><LT><LT>
:nnoremap <Tab> >>
:nnoremap <S-Tab> <LT><LT>
:vnoremap <Tab> >
:vnoremap <S-Tab> <LT>
Note that, the <S-Tab> mapping will work only if Vim receives the correct
key sequence. This is mostly the case with GUI Vim.
For more information, read
:help :inoremap
:help :nnoremap
:help :vnoremap
:help <S-Tab>
:help i_CTRL-O
:help >
:help <<
:help <LT>
20.11. In my mappings the special characters like <CR> are not recognized.
How can I configure Vim to recognize special characters?
Check the value of the 'cpoptions' option:
:set cpoptions?
If this option contains the '<' flag, then special characters will not be
recognized in mappings. Remove the '<' flag from 'cpoptions' option:
:set cpo-=<
Also, check the value of the 'compatible' option:
:se compatible?
The 'compatible' option must be reset:
:se nocompatible
For more information, read
:help 'cpoptions'
:help 'compatible'
20.12. How do I use the '|' to separate multiple commands in a map?
You can escape the '|' character using backslash (\) to use '|' in a map.
:map _l :!ls \| more<CR>
You can also try the following command:
:map _l :!ls <bar> more<CR>
There are also other ways to do this.
For more information, read
:help map_bar
20.13. If I have a mapping/abbreviation whose ending is the beginning of
another mapping/abbreviation, how do I keep the first from expanding
into the second one?
Instead of using the ":map lhs rhs" command, use the ":noremap lhs rhs"
command. For abbreviations, use "noreabbrev lhs rhs". The "nore" prefix
prevents the mapping or abbreviation from being expanded again.
For more information, read
:help :noremap
:help :noreabbrev
20.14. Why does it take a second or more for Vim to process a key,
sometimes when I press a key?
Make sure you have not defined a mapping for this key using the following
command:
:map <key>
If a mapping is defined for this key and the mapped key contains more than
one character, then Vim will wait for the next character to be pressed to
determine whether it is the mapped key or not. For example, if you have
mapped "ab", then if you press "a", Vim will wait for the next key to be
pressed. If the next key is "b", Vim will execute the mapped sequence.
Otherwise, Vim will proceed with the normal processing of "a" followed by
the next key. If the 'timeout' option is set (which is the default), then
Vim will timeout after waiting for the period specified with the
'timeoutlen' option (default is 1 second).

20.15. How do I map a key to run an external command using a visually
selected text?
You can the ":vmap" command to map a key in the visual mode. In the mapped
command sequence, you have to first yank the text. The yanked text is
available in the '"' register. Now, you can use the contents of this
register to run the external command. For example, to run the external
command "perldoc" on a visually selected text, you can use the following
mapping:
:vmap <F7> y:!exec "!perldoc '" . @" . "'"<CR>
If you want the mapping to work in the visual mode, but not with the
highlighted text, you can use the following command:
:vmap <F7> :<C-U>!perldoc <cword><CR>
The above mapping will use the word under the cursor instead of the
highlighted text. Note the use of the <C-U> before invoking the "perldoc"
external command. The <C-U> is used to erase the range of text selected in
the visual mode and displayed on the command line. If the visual range is
not removed using <C-U>, then the output from the external command will
replace the visually selected text.

:help c_CTRL-U
:help :!cmd
20.16. How do I map the Ctrl-I key while still retaining the functionality
of the <Tab> key?
The Ctrl-I key and the <Tab> key produce the same keycode, so Vim cannot
distinguish between the Ctrl-I and the <Tab> key. When you map the Ctrl-I
key, the <Tab> key is also mapped (and vice versa). The same restriction
applies for the Ctrl-[ key and the <Esc> key.

SECTION 21 - ABBREVIATIONS
21.1. How do I auto correct misspelled words?
You can auto correct misspelled words using abbreviations. For example, the
following abbreviation can be used to correct "teh" with "the":
:abbreviate teh the
Vim supports abbreviations in insert mode, replace mode and command-line
mode.
For more information, read
:help 24.7
:help abbreviations
:help Q_ab
21.2. How do I create multi-line abbreviations?
You can create multi-line abbreviations by embedding the "<CR>"
key code in the text:
iabbrev #c --------------<CR>-- Date:<CR>--<CR>---------
With the above abbreviation, when you type #c, it will be expanded to
the following text:
--------------
-- Date:
--
---------
For more information, read
:help abbreviations
21.3. When my abbreviations are expanded, an additional space character is
added at the end of the expanded text. How do I avoid this character?
To avoid an additional space character at the end of the expanded text, you
can expand the abbreviation by pressing the CTRL-] key. The abbreviation
will be expanded without adding a space character at the end.
Another alternative is to use the following function and command:
function! Eatchar(pat)
let c = nr2char(getchar())
return (c =~ a:pat) ? '' : c
endfunction
command! -nargs=+ Iabbr execute "iabbr" <q-args> . "<C-R>=Eatchar('\\s')<CR>"
Now, define your abbreviations using the new "Iabbr" command instead of the
builtin "iabbrev" command. With this command, after expanding the
abbreviated text, the next typed space character will be discarded.
For more information, read
:help abbreviations
21.4. How do I insert the current date/time stamp into the file?
You can use the strftime() function to insert the current data/time stamp
in a file. For example, you can use the following abbreviation:
iabbrev dts <C-R>=strftime("%y/%m/%d %H:%M")<CR>
With this abbreviation, when you type dts in insert mode, it will be
expanded to the date/time stamp.
Some other forms of the above abbreviation are listed below:
iabbrev mdyl <C-R>=strftime("%a %d %b %Y")<CR>
iabbrev mdys <C-R>=strftime("%y%m%d")<CR>
iabbrev mdyc <C-R>=strftime("%c")<CR>
iabbrev hml <C-R>=strftime("%d/%m/%y %H:%M:%S")<CR>
iabbrev hms <C-R>=strftime("%H:%M:%S")<CR>
For more information, read
:help strftime()
:help i_CTRL-R
21.5. How do I prevent an abbreviation from expanding in insert mode?

repeat the last simple change like a insert, delete, change, paste, etc.
For more information, read
:help 04.3
:help single-repeat
:help Q_re
22.2. How I record and repeat a set of key sequences?
You can use the 'q' command in normal mode to record a set of key sequences
and store it in a register. For example, in the normal mode you can press q
followed by a register name {0-9a-bA-Z"} to start the recording. To
end/stop the recording press q again. You can playback/repeat the recorded
key sequences by pressing @ followed by the register name. e.g. @a.
Another approach is to start Vim with the "-w" command-line argument.
$ vim -w <file_name>
Vim will record all the characters typed in the session in the
specified file "file_name". You can use the recorded file with the "-s"
command line argument to play it back:
$ vim -s <file_name>
For more information, read
:help 10.1
:help recording
:help -w
:help -s
22.3. How do I edit/modify a recorded set of key sequences?
The recorded key sequences are stored in a register. You can paste the
contents of the register into a Vim buffer, edit the pasted text and again
yank the text into the register. You can also use the ":let" command to
modify the register. For example:
:let @a = "iHello World\<Esc>"
For more information, read
:help recording
:help 10.1
:help let-register
:help <>
:help 'cpoptions'
22.4. How do I write recorded key sequences to a file?
The recorded key sequences are stored in a register. You can paste the
contents of the register into a Vim buffer. Now you can save the buffer
into a file. You can also modify the pasted text and again yank into the
register to modify the recorded key sequence. For example, if you record a
set of key sequences using qa ..... q. The recorded key sequences are
stored in the register 'a'. You can paste the contents of register 'a'
using "ap.
For more information, read
:help recording
:help 10.1
22.5. I am using register 0 to record my key sequences (i.e. q0 .... q).
In the recorded key sequences, I am yanking some text. After the
first replay of the recorded key sequence, I am no longer able to
play it back.
Register 0 contains the text from the last yank operation. In your recorded
key sequence, when the yank is performed, register 0 is overwritten with
the yanked text. So your recording stored in register 0 is lost. You have
to use some other register.
For more information, read
:help registers

For more information, read
:help :colorscheme
24.8. Vim syntax highlighting is broken. When I am editing a file, some
parts of the file is not syntax highlighted or syntax highlighted
incorrectly.
Vim doesn't read the whole file to parse the text for syntax highlighting.
It starts parsing wherever you are viewing the file. That saves a lot of
time, but sometimes the colors are wrong. A simple fix is refreshing the
screen using the CTRL-L key. Or scroll back a bit and then forward again.
You can also use the command:
:syntax sync fromstart
Note that this might considerably slow down the screen refreshing.
For more information, read
:help :syn-sync
:help :syn-sync-first
24.9. Is there a built-in function to syntax-highlight the corresponding
matching bracket?
No. Vim doesn't support syntax-highlighting matching brackets. You can try
using the plugin developed by Charles Campbell:

25.12. How do I get the current visually selected text into a Vim variable
or register?
You can get the current visually selected text into a Vim variable by
yanking the text into Vim register and then assigning the contents of the
register into the variable:
:normal! gvy
:let myvar = @"
The above command copies the visually selected text into the variable
"myvar".
You can also use the command:
:normal! gv"*y
In the above command, gv reselects the last visually selected text and the
rest of the command copies the selected text into the * (clipboard)
register. Alternatively, you can set the 'a' flag in the 'guioptions'
option to automatically copy a visually selected text into the * register.
To do this as part of a visual map, you can use a command similar to the
one shown below:
:vmap <F3> "*y:call ...

25.17. How do I get the character under the cursor from a Vim script?
You can use the getline() function and use string index [] to get the
character:
:echo getline(".")[col(".") - 1]
In the above command, getline(".") returns the text in the current line.
The indexing of the string starts at zero, and you can get a single
character in a string by its index with the "string[index]" notation. The
col(".") returns the column of the cursor position; the adjustment is to
get the right character of the string.
Alternatively, you can use the following sequence of commands to get the
character under the cursor:
normal! vy
let ch=@"
Note that the above commands will change the '< and '> marks.
For more information, read

:help line-continuation
25.26. When I try to "execute" my function using the "execute 'echo
Myfunc()'" command, the cursor is moved to the top of the current
buffer. Why?
The ":execute" command runs the normal mode command specified by the
argument. In the case of the following command:
:execute "echo Myfunc()"
The call to "echo Myfunc()" will return 0. The ":execute" command will run
the normal mode command "0", which moves the cursor to the top of the file.
To call a Vim function, you should use the ":call" command instead of the
":execute" command:
:call Myfunc()

For more information, read
:help :@
25.28. After calling a Vim function or a mapping, when I press the 'u'
key to undo the last change, Vim undoes all the changes made by
the mapping/function. Why?
When you call a function or a mapping, all the operations performed by the
function/mapping are treated as one single operation. When you undo the
last operation by pressing 'u', all the changes made by the
function/mapping are reversed.
For more information, read
:help undo-redo
:help map-undo
25.29. How can I call a function defined with s: (script local function)
from another script/plugin?
The s: prefix for a Vim function name is used to create a script local
function. A script local function can be called only from within that
script and cannot be called from other scripts. To define a function in a
script/plugin, so that it can be called from other plugins/scripts, define
the function without the s: prefix.

SECTION 26 - PLUGINS
26.1. How do I set different options for different types of files?
You can create filetype plugins to set different options for different
types of files. You should first enable filetype plugins using the command:
:filetype plugin on
A filetype plugin is a vim script that is loaded whenever Vim opens or
creates a file of that type. For example, to ensure that the 'textwidth'
option is set to 80 when editing a C program (filetype 'c'), create one of
the following files:
~/.vim/ftplugin/c.vim (Unix)
%HOME%\vimfiles\ftplugin\c.vim (Windows)
with the following text in it:
setlocal textwidth=80
You can also use autocommands to set specific options when editing specific
type of files. For example, to set the 'textwidth' option to 75 for only
*.txt files, you can use the following autocmd:
autocmd BufRead *.txt setlocal textwidth=80
For more information, read
:help filetype-plugin
:help add-filetype-plugin
:help autocmd
:help 40.3
26.2. I have downloaded some Vim plugins, syntax files, indent files, color
schemes, filetype plugins, etc from the web. Where should I copy
these files so that Vim will find them?
You can place the runtime files (plugins, syntax files, indent files, color
schemes, filetype plugins, etc) under one of the directories specified by
the 'runtimepath' option. For Unix systems, this is usally the "$HOME/.vim"
directory. For MS-Windows systems, this is usually the $VIM\vimfiles or
$HOME\vimfiles directory. Depending on the type of the runtime file, you
have to place it under a specific directory under the above runtime
directory. The names of the directories are listed below:
colors/ - color scheme files
compiler/ - compiler files
doc/ - documentation
ftplugin/ - filetype plugins
indent/ - indent scripts
keymap/ - key mapping files
lang/ - menu translations
plugin/ - plugin scripts
syntax/ - syntax files
tutor/ - files for vimtutor
For more information, read
:help your-runtime-dir
:help 'runtimepath'
:help :runtime
26.3. How do I extend an existing filetype plugin?
You can extend an existing filetype plugin by creating a file under either
the $VIMRTUNTIME/after/ftplugin or the $VIMRTUNTIME/ftplugin directory. The
name of the file should be the same as the name of the existing filetype
plugin file. You can place your additions to the new file.
If you placed the file in the after/ftplugin runtime directory, then Vim
will first source the existing filetype plugin file and then will source
the new file. If you placed the file in the $VIMRTUNTIME/ftplugin runtime
directory, then Vim will first source the new file and then will source the
existing filetype plugin file.
For more information, read
:help ftplugin-overrule
:help filetype-plugin
:help add-filetype-plugin
:help 'runtimepath'
26.4. How do I turn off loading the Vim plugins?
You can reset the 'loadplugins' option to turn off loading the plugins:
:set noloadplugins
You can also specify the "--noplugin" command line argument to stop loading
the plugins:
$ vim --noplugin
For more information, read
:help 'loadplugins'
:help --noplugin
:help load-plugins
26.5. How do I turn on/off loading the filetype plugins?
By default, Vim will not load the filetype plugins. You can configure Vim
to load filetype plugins using the command:
filetype plugin on
You can turn off loading the filetype plugins using:
filetype plugin off
For more information, read
:help filetype-plugin-on
:help filetype-plugin-off
:help :filetype
26.6. How do I override settings made in a file type plugin in the global
ftplugin directory for all the file types?
You can use an autocommand triggered on the FileType event:
au Filetype * set formatoptions=xyz
This should at least be after "filetype on" in your vimrc. Best is to put
it in your "myfiletypefile" file, so that it's always last.
If you want to override a setting for a particular filetype, then create a
file with the same name as the original filetype plugin in the
~/.vim/after/ftplugin directory For example, to override a setting in the
c.vim filetype plugin, create a c.vim file in the ~/.vim/after/ftplugin
directory and add your preferences in this file.
For more information, read
:help ftplugin-overrule
:help ftplugins
:help myfiletypefile
26.7. How do I disable the Vim directory browser plugin?
To disable the directory browsing Vim plugin, add the following line to
your .vimrc file:
let loaded_explorer = 1
For more information, read
:help file-explorer
26.8. How do I set the filetype option for files with names matching a
particular pattern or depending on the file extension?
You can set the 'filetype' option for files with names matching a
particular pattern using an autocmd. For example, to set the 'filetype'
option to 'c' for all files with extension '.x', you can use the following
autocmd:
autocmd! BufRead,BufNewFile *.x setfiletype c
A better alternative to the above approach is to create a filetype.vim file
in the ~/.vim directory (or in one of the directories specified in the
'runtimepath' option) and add the following lines:
" my filetype file
if exists("did_load_filetypes")
finish
endif
augroup filetypedetect
au! BufRead,BufNewFile *.x setfiletype c
augroup END

You can use '[{' command to jump to the beginning of the code block and ']}
to jump to the end of the code block from inside the block.
For more information, read
:help [{
:help ]}
:help various-motions
27.7. Is there a way to turn off the "//" comment auto-insertion behavior
for C++ files? If I'm sitting on a line beginning with "//", then I
open a new line above or below it, Vim automatically inserts new "//"
chars.
You can modify the value of the 'comments' option to stop Vim from
inserting the C++ comment character ("//") automatically. For example:
:set comments=sr:/*,mb:*,el:*/
For more information, read
:help 'comments'
:help format-comments
27.8. How do I add the comment character '#' to a set of lines at the
beginning of each line?
First, select the first character in all the lines using visual block mode
(CTRL-V). Press 'I' to start inserting characters at the beginning of the
line. Enter the comment character and then stop the insert mode by pressing
<Esc>. Vim will automatically insert the entered characters at the
beginning of all the selected lines.
For more information, read
:help visual-block
:help blockwise-operators
:help v_b_I
27.9. How do I edit a header file with the same name as the corresponding C
source file?
You can use the following command to edit a header file with the same name
as the corresponding C source file:
:e %:t:r.h
You can use the following command to edit the file in a new split window:
:sp %:t:r.h
In the above commands, the percent sign expands to the name of the current
file. The ":t" modifier extracts the tail (last component) of the
filename. The ":r" modifier extracts the root of the filename. The .h is
appended to the resulting name to get the header filename.
Another approach is to use the following command:
:sfind %:t:r.h
This command will search for the header file in the directories specified
in the 'path' option.
For more information, read
:help cmdline-special
:help filename-modifiers
:help :sfind
:help 'path'
27.10. How do I automatically insert comment leaders while typing comments?
To automatically insert comment leaders while typing comments, add the 'r'
and 'o' flags to the 'formatoptions' option.
:set formatoptions+=ro
You may also want to add the 'c' flag to auto-wrap comments using the
'textwidth' option setting and the 'q' flag to format comments with the
"gq" command:
:set formatoptions=croq
For more information, read
:help 30.6
:help format-comments
:help 'comments'
:help fo-table
=============================================================================
SECTION 28 - QUICKFIX
28.1. How do I build programs from Vim?
You can use the ":make" command to build programs from Vim. The ":make"
command runs the program specified by the 'makeprg' option.
For more information, read
:help 30.1
:help make_makeprg
:help 'makeprg'
:help 'makeef'
:help :make
:help quickfix
28.2. When I run the make command in Vim I get the errors listed as the
compiler compiles the program. When it finishes this list disappears
and I have to use the :clist command to see the error message again.
Is there any other way to see these error messages?
You can use the ":copen" or ":cwindow" command to open the quickfix window
that contains the compiler output. You can select different error lines
from this window and jump to the corresponding line in the source code.
For more information, read
:help :copen
:help :cwindow
:help quickfix
=============================================================================
SECTION 29 - FOLDING
29.1. How do I extend the Vim folding support?
You can use the 'foldexpr' option to fold using an user specified function.
For example, to fold subroutines of the following form into a single line:
sub foo {
my $barf;
$barf = 3;
return $barf;
}
You can use the following commands:
set foldmethod=expr
set foldexpr=MyFoldExpr(v:lnum)
fun! MyFoldExpr(line)
let str = getline(a:line)
if str =~ '^sub\>'
return '1'
elseif str =~ '^}'
return '<1'
else
return foldlevel(a:line - 1)
endif
endfun
For more information, read
:help 'foldexpr'
:help fold-expr
29.2. When I enable folding by setting the 'foldmethod' option, all the
folds are closed. How do I prevent this?
You can set the 'foldlevelstart' option to a particular value to close only
folds above the specified value.
:set foldlevelstart=99
For more information, read
:help 'foldlevelstart'
:help 'foldlevel'
:help fold-foldlevel
29.3. How do I control how many folds will be opened when I start editing a
file?
You can modify the 'foldlevelstart' option to control the number of folds
that will be opened when you start editing a file. To start editing with
all the folds closed:
:set foldlevelstart=0
For more information, read
:help 'foldlevelstart'
29.4. How do I open and close folds using the mouse?
You can click on the + and - characters displayed at the leftmost column to
open and close fold. For this to work, you have to set the 'foldcolumn'
to a value greater than zero:
:set foldcolumn=2
For more information, read

29.5. How do I change the text displayed for a closed fold?
You can use the 'foldtext' option to change the text displayed for a closed
fold.
For more information, read
:help 'foldtext'
:help fold-foldtext
:help 'fillchars'
29.6. How do I store and restore manually created folds across different
Vim invocations?
You can use the ":mkview" command to store manually created folds. Later,
you can use the ":loadview" command to restore the folds. For this to work,
the 'viewoptions' must contain "folds".

=============================================================================
SECTION 30 - VIM WITH EXTERNAL APPLICATIONS
30.1. Can I run a shell inside a Vim window?
Currently Vim doesn't have support for running shell and other external
commands inside a Vim window.
For more information, read
:help shell-window
Alternatively, you can try using the Unix "screen" utility or the 'splitvt'
program.
You can also use the vimsh plugin by Brian Sturk to run a shell in a Vim
window. To use this you need to have Vim built with python support. For
more information visit the following URL:
http://vim.sourceforge.net/scripts/script.php?script_id=165
30.2. How do I pass the word under the cursor to an external command?
You can use the special keyword <cword> to pass the word under the cursor
to an external command. For example:
:!dict <cword>
For more information, read
:help <cword>
30.3. How do I get the output of a shell command into a Vim buffer?
You can use the ":r !" command to get the output of a shell command into a
Vim buffer:
:r !ls
For more information, read
:help :r!
30.4. How do I pipe the contents of the current buffer to an external
command and replace the contents of the buffer with the output from
the command?
You can use the :! command to pipe the contents of the current buffer to a
external command and replace the contents of the buffer with the output
from the command. For example, to sort the contents of the current buffer,
using the Unix sort command, you can use the following command:
:%!sort
To sort only lines 10-20, you can use the following command
:10,20!sort
Also, if you want to pipe a buffer to an external command but not put the
results back in the buffer, you can use
:w !sort
The above command will pipe the entire buffer to the sort command. Note
that the space between the 'w' and the '!' is critical. To pipe only a
range of lines, you can use
:10,20w !sort
The above command will pipe the lines 10-20 to the sort command.
For more information, read
:help :range!
:help 10.9
:help :w_c
30.5. How do I sort a section of my file?
You can pipe a section of the file to the Unix "sort" utility to sort the
file. For example:
:5,100!sort
You can also use a visual block, and use the "!sort" command on the
selected block.
To sort using visual blocks (sort based on a column or sort just the column
itself), read the following tip from the Vim online web page:
http://vim.sourceforge.net/tips/tip.php?tip_id=588
30.6. Is there a step-by-step guide for using Vim with slrn?
Visit the following link to get information about using Vim with Slrn:
http://thingy.apana.org.au/~fun/slrn/
30.7. How do I use Vim as a pager?
You can use Vim as a pager using the $VIMRUNTIME/macros/less.sh shell
script, supplied as part of the standard Vim distribution. This shell
script uses the $VIMRUNTIME/macros/less.vim Vim script to provide less like
key bindings.
For more information, read
:help less
30.8. How do I view Unix man pages from inside Vim?
You can view Unix man pages, inside Vim, using the man.vim plugin supplied
as part of the standard Vim distribution. To use this plugin, add the
following line to your startup vimrc file:
runtime ftplugin/man.vim
You can also press the K key to run the program specified by the
'keywordprg' option with the keyword under the cursor. By default,
'keywordprg' is set to run man on the keyword under the cursor.
For more information, read
:help man-plugin
:help K
:help 'keywordprg'
30.9. How do I change the diff command used by the Vim diff support?
By default, the Vim diff support uses the 'diff' command. You can change
this by changing the 'diffexpr' option.
For more information, read
:help diff-diffexpr
:help 'diffexpr'
30.10. How do I use the Vim diff mode without folding?
You can use the following command-line to start Vim with two filenames
and use the diff mode without folding:
$ vim -o file1 file2 "+windo set diff scrollbind scrollopt+=hor nowrap"
If you like vertically split windows, then replace "-o" with "-O".
For more information, read
:help vimdiff
=============================================================================
SECTION 31 - GUI VIM
31.1. How do I create buffer specific menus?
Adding support for buffer specific menus is in the Vim TODO list. In the
mean time, you can try Michael Geddes's plugin, buffermenu.vim:
http://vim.sourceforge.net/scripts/script.php?script_id=246
31.2. How do I change the font used by GUI Vim?
You can change the 'guifont' option to change the font used by GUI Vim. To
display the current value of this option, you can use
:set guifont?
You can add the displayed font name to the .vimrc file to use the font
across Vim sessions. For example, add the following line to the .vimrc file
to use Andale Mono font.
set guifont=Andale_Mono:h10:cANSI
For Win32, GTK and Photon version of Vim, you can use the following command
to bringup a dialog which will help you in changing the guifont:
:set guifont=*
You can also use the -font Vim command line option to specify the font used
for normal text.
For more information, read
:help 'guifont'
:help 'guifontset'
:help 'guifontwide'
:help font-sizes
:help -font

31.3. When starting GUI Vim, how do I specify the location of the GVIM
window?
You can use the "-geometry" command line argument to specify the location
of the GUI Vim window. For example:
$ gvim -geometry 80x25+100+300
For more information, read
:help 31.4
:help -geom
31.4. How do I add a horizontal scrollbar in GVim?
You can enable the horizontal scrollbar by modifying the 'guioptions'
option:
:set guioptions+=b
For more information, read
:help 'guioptions'
:help gui-horiz-scroll
31.5. How do I make the scrollbar appear in the left side by default?
You can add the 'l' flag to the 'guioptions' option to make the scrollbar
appear in the left side.
:set guioptions+=l
:set guioptions-=r
For more information, read
:help 'guioptions'
:help gui-scrollbars
31.6. How do I remove the Vim menubar?
You can remove the Vim menubar by removing the 'm' flag from the
'guioptions' option:
:set guioptions-=m
For more information, read
:help 'guioptions'
31.7. I am using GUI Vim. When I press the ALT key and a letter, the menu
starting with that letter is selected. I don't want this behavior as
I want to map the ALT-<key> combination. How do I do this?
You can use the 'winaltkeys' option to disable the use of the ALT key to
select a menu item:
:set winaltkeys=no
For more information, read
:help 'winaltkeys'
:help :simalt
31.8. Is it possible to scroll the text by dragging the scrollbar so that
the cursor stays in the original location?
The way Vim is designed, the cursor position has to be in a visible spot in
normal, visual, select and insert mode. This cannot be changed without
modifying Vim. When the scrollbar is used, the cursor will be moved so that
it is always visible. Another approach to solving this problem is to use
the Vim marks. You can mark the current cursor position using ma. Then
scroll to a different part of the text and jump back to the old position
using `a. You can also try the following suggestion from the Vim Online
website:
http://www.vim.org/tip_view.php?tip_id=320
For more information, read
:help mark-motions
31.9. How do I get gvim to start browsing files in a particular directory
when using the ":browse" command?
You can set the 'browsedir' option to the default directory to use for the
":browse" command.
:set browsedir='<your_dir>'
For more information, read
:help 'browsedir'
31.10. For some questions, like when a file is changed outside of Vim, Vim
displays a GUI dialog box. How do I replace this GUI dialog box with
a console dialog box?
You can set the 'c' flag in the 'guioptions' option to configure Vim to use
console dialogs instead of GUI dialogs:
:set guioptions+=c
For more information, read
:help 'guioptions'
31.11. I am trying to use GUI Vim as the editor for my xxx application.
When the xxx application launches GUI Vim to edit a file, the
control immediately returns to the xxx application. How do I start
GUI Vim, so that the control returns to the xxx application only
after I quit Vim?
You have to start GUI Vim with the '-f' (foreground) command line option:
$ gvim -f
By default, GUI Vim will disconnect from the program that started Vim. With
the '-f' option, GUI Vim will not disconnect from the program that started
it.
For more information, read
:help gui-fork
:help -f
31.12. Why does the "Select Font" dialog doesn't show all the fonts
installed in my system?
Vim supports only fixed width (mono-spaced) fonts. Proportional fonts are
not supported. In the "Select Font" dialog, only fixed width fonts will be
displayed.
For more information, read
:help font-sizes
:help 'guifont'
31.13. How do I use the mouse in Vim command-line mode?
You can set the 'c' flag in the 'mouse' option to use mouse in the Vim
command-line mode:
:set mouse+=c
For more information, read
:help mouse-using

31.14. When I use the middle mouse button to scroll text, it pastes the
last copied text. How do I disable this behavior?
You can map the middle mouse button to <Nop> to disable the middle mouse
button:
:map <MiddleMouse> <Nop>
:map! <MiddleMouse> <Nop>
For more information, read
:help gui-mouse-mapping
:help <Nop>
31.15. How do I change the location and size of a GUI Vim window?
You can use the "winpos" command to change the Vim window position. To
change the size of the window, you can modify the "lines" and "columns"
options.
For example, the following commands will position the GUI Vim window at the
X,Y co-ordinates 50,50 and set the number of lines to 50 and the number of
columsn to 80.
:winpos 50 50
:set lines=50
:set columns=80
The arguments to the 'winpos' command specify the pixel co-ordinates of the
Vim window. The 'lines' and 'columns' options specify the number of lines
and characters to use for the height and the width of the window
respectively.

=============================================================================
SECTION 32 - VIM ON UNIX
32.1. I am running Vim in a xterm. When I press the CTRL-S key, Vim
freezes. What should I do now?
Many terminal emulators and real terminal drivers use the CTRL-S key to
stop the data from arriving so that you can stop a fast scrolling display
to look at it (also allowed older terminals to slow down the computer so
that it did not get buffer overflows). You can start the output again by
pressing the CTRL-Q key.
When you press the CTRL-S key, the terminal driver will stop sending the
output data. As a result of this, it will look like Vim is hung. If you
press the CTRL-Q key, then everything will be back to normal.
You can turn of the terminal driver flow control using the 'stty' command:
$ stty -ixon -xoff
or, you can change the keys used for the terminal flow control, using the
following commands:
$ stty stop <char>
$ stty start <char>
32.2. I am seeing weird screen update problems in Vim. What can I do to
solve this screen/display update problems?
You have to use a proper terminal emulator like xterm with correct TERM
settings (TERM=xterm) and a correct terminfo/termcap file.
For more information, read
:help 'term'
32.3. I am using the terminal/console version of Vim. In insertmode, When I
press the backspace key, the character before the cursor is not
erased. How do I configure Vim to do this?
You have to make sure that Vim gets the correct keycode for the backpspace
key. You can try using the command:
:fixdel
Make sure the TERM environment variable is set to the correct terminal
name. You can try using the 'stty' command:
$ stty erase ^H
where, you have to enter the ^H character by pressing the CTRL-V key and
then the CTRL-H key.
For more information, read
:help :fixdel
:help Linux-backspace
:help NetBSD-backspace
32.4. I am using Vim in a xterm. When I quit Vim, the screen contents are
restored back to the original contents. How do I disable this?
The xterm has a capability called "alternate screen". If this capability
is present, vim switches to that alternate screen upon startup and back on
exit, thus restoring the original screen contents. To disable this
feature, add the following line to your .vimrc file:
:set t_ti= t_te=
For more information, read
:help restorescreen
:help xterm-screens
32.5. When I start Vim, it takes quite a few seconds to start. How do I
minimize the startup time?
This may be related to Vim opening the X display for setting the xterm
title and using the X clipboard. Make sure the DISPLAY variable is set to
point to the correct host. Try using the command line:
$ vim -X
This will prevent Vim from opening the X display. With this command-line
option, the X clipboard cannot be used and also Vim will not be able to
change the xterm title.
You can also set the 'clipboard' option to
:set clipboard=exclude:.*
This has the same effect as using the -X command-line argument.
For more information, read
:help -X
:help 'clipboard'
32.6. How can I make the cursor in gvim in unix stop blinking?
You can modify the 'guicursor' option, to stop the cursor from blinking.
For example:
:set guicursor=a:blinkon0
For more information, read
:help 'guicursor'
32.7. How do I change the menu font on GTK Vim?
You can modify the ~/.gtkrc file to change the menu font on GTK Vim. For
example:
style "default"
{ font ="smooth09" }
class "*" style "default"
The last line changes the font of all widgets.
For more information, read
:help gui-gtk
32.8. How do I prevent <Ctrl-Z> from suspending Vim?
You can map <Ctrl-Z> to prevent the suspending. Here are some suggestions:
- Make <Ctrl-Z> do nothing:
:map <C-Z> <Nop>
- Make <Ctrl-Z> start a shell:
:map <C-Z> :shell<CR>
- Make <Ctrl-Z> give an error message::
:map <C-Z> :"suspending disabled<CR>
For the last example, the double quote is necessary in order to keep the
message on the status line.
32.9. When I kill the xterm running Vim, the Vim process continues to run
and takes up a lot of CPU (99%) time. Why is this happening?
When Vim is built with support for Python interface, you will have this
problem. This is a known problem with the python thread library and Vim. To
solve this problem, use a Vim binary built without the Python interface.
For more information, read
:help +python
:help python
32.10. How do I get the Vim syntax highlighting to work in a Unix terminal?
The easiest and simplest way to get Vim syntax highlighting is to use the
GUI version of Vim (GVIM). To get syntax highlighting to work in the
console/terminal version of Vim, you have to run a terminal emulator (like
Xfree86 xterm or rxvt or dtterm) that supports color. Note that if a
terminal emulator supports changing the background and foreground colors,
that does not mean that it also supports ANSI escape sequences for changing
the color. You can download the latest version of Xfree86 xterm from
http://dickey.his.com/xterm/xterm.html. You can download the latest version
of rxvt from http://www.rxvt.org. You have to install the terminfo/termcap
file that supports colors for the terminal emulator. Also, set the TERM
environment variable to the correct name of the term that supports colors.
You can use the colortest.vim script supplied with the Vim runtime
package to test the color setup. To use this script, follow these steps:
:e $VIMRUNTIME/syntax/colortest.vim
:source %

SECTION 33 - VIM ON MS-WINDOWS
33.1. In MS-Windows, CTRL-V doesn't start the blockwise visual mode. What
happened?
The mswin.vim script provides key mappings and options to make Vim behave
like a MS-Windows application. One of the keys mapped is CTRL-V which is
used for pasting text in MS-Windows applications. This will disable the use
of CTRL-V to start the blockwise visual mode. The mswin.vim script maps
CTRL-Q for staring the blockwise visual mode. So you can use CTRL-Q instead
of CTRL-V.
For more information, read
:help CTRL-V
:help CTRl-V-alternative
:help CTRL-Q
:help 10.5
33.2. When I press the CTRL-Y key, it acts like the CTRL-R key. How do I
configure Vim to treat CTRL-Y as CTRL-Y?
The mapping of the CTRL-Y key to the CTRL-R key is done by the mswin.vim
script. The mswin.vim script maps CTRL-Y to make Vim behave like a standard
MS-Windows application. This is explained in ":help CTRL-Y". You can either
comment out the line in mswin.vim that maps the CTRL-Y key or you can
remove the line in your .vimrc file that sources the mswin.vim script.
33.3. How do I start GUI Vim in a maximized window always?
You can use the "simalt" command to maximize the Vim window. You can use
the GUIEnter autocmd to maximize the Vim window on startup:
autocmd GUIEnter * simalt ~x
For more information, read
:help :simalt
:help GUIEnter
:help gui-win32-maximized
33.4. After doing some editing operations, Vim freezes. The cursor becomes
an empty rectangle. I am not able enter any characters. What is
happening?
Most probably, you used the mouse wheel to scroll the text in Vim. There is
a known problem in using intellimouse mouse wheel with Vim. To avoid this
problem, disable Universal scrolling support for Vim.
For more information, read
:help intellimouse-wheel-problems
33.5. I am using Windows XP, the display speed of maximized GVim is very
slow. What can I do to speed the display updates?
This may be due to the fact that you have enabled 'Smooth edges of screen
fonts' in the display properties. Try turning off font smoothing or try
changing the smoothing method to "Standard".
33.6. What are the recommended settings for using Vim with cygwin?
You may want to set the following shell related Vim settings:
:set shellcmdflag=-c
:set shellquote=
:set shellslash " Use the forward slash for expansion.
:set shellxquote=\"
:set shell=d:\cygwin\bin\bash.exe " Use the bash shell
:set shellpipe=2>&1| tee
:set shellredir=>%s 2>&1
33.7. I am trying to use GNU diff with Vim diff mode. When I run the diff
from command line, it works. When I try to use the diff with Vim it
doesn't work. What should I do now?
There is a problem with using GNU diff with Vim. You can try using the
GNU diff.exe built by Ron Aaron from the following link:
http://www.mossbayeng.com/~ron/vim/builds.html
33.8. Is it possible to use Vim as an external editor for MS-Windows
Outlook email client?
You can use the "cubiclevim" COM Add-In to use Vim as an external editor
for MS-Windows Outlook email client. Visit the following URL for more
information:
http://sourceforge.net/projects/cubiclevim
Note that currently this works only with MS-Office 2000 and XP.
33.9. I am using Vim to edit HTML files. How do I start internet explorer
with the current file to preview the HTML file?
You can use the following command:
:!start c:\progra~1\intern~1\iexplore.exe file://%:p<CR>
33.10. I would like to use Vim with Microsoft Visual Studio. How do I do
this?
You have to download and use the OLE version of Vim (for example:
gvim61ole.zip). This file also contains instructions on how to use Vim with
Visual Studio.
For more information, read
:help MSVisualStudio
33.11. Where do I place the _vimrc and _gvimrc files?
You can place the _vimrc and _gvimrc files under the directory pointed to
by the VIM environment variable. If you are sharing this system with other
users, then you can place the files in a directory and set the HOME
environment variable to this directory.
For more information, read
:help $HOME-use
:help _vimrc
33.12. Everytime I save a file, Vim warns about the file being changed
outside of Vim. Why?
If you get the following warning message, everytime you save a file:
WARNING: The file has been changed since reading it!!!
Do you really want to write to it (y/n)?
then this problem could be related to a bug in MS-Windows on the day
daylight saving time starts. Vim remembers the timestamp of the file after
it was written. Just before the next write the timestamp is obtained again
to check if the file was changed outside of Vim. This works correctly,
except on the day daylight saving time starts.
This problem will go away the next day after the day the daylight saving
time starts.
For more information, read
:help W11
=============================================================================
SECTION 34 - PRINTING
34.1. How do I print a file along with line numbers for all the lines?
You can set the 'printoptions' option and use the ":hardcopy" command to
print your file:
:set printoptions=number:y
:hardcopy
For more information, read
:help 'printoptions'
:help :hardcopy
34.2. How do I print a file with the Vim syntax highlighting colors?
You can use the ":hardcopy" command to print a file with the Vim syntax
highlighting colors. You can also convert your file to a HTML file using
the 2html.vim script and print the HTML file.
For more information, read
:help syntax-printing
:help 2html.vim
:help :hardcopy
:help printing
=============================================================================
SECTION 35 - BUILDING VIM FROM SOURCE
35.1. How do I build Vim from the sources on a Unix system?
For a Unix system, follow these steps to build Vim from the sources:
- Download the source and run-time filles archive (vim-##.tar.bz2) from the
ftp://ftp.vim.org/pub/vim/unix directory.
- Extract the archive using the bzip2 and tar utilities using the command:
$ bunzip2 -c <filename> | tar -xf -
- Run the 'make' command to configure and build Vim with the default
configuration.
- Run 'make install' command to installl Vim in the default directory.
To enable/disable various Vim features, before running the 'make' command
you can run the 'configure' command with different flags to include/exclude
the various Vim features. To list all the available options for the
'configure' command, use:
$ configure -help
For more information, read
:help install
35.2. How do I install Vim in my home directory or a directory other
than the default installation directory in Unix?
To install Vim in a directory other than the default installation
directory, you have to specify the directory using the --prefix option
while running the configure script.
$ ./configure --prefix=/users/xyz
You can enable/disable various Vim feature by supplying different arguments
to the configure script. For more information about all these options, run
$ ./configure --help
For more information, read
:help install-home
:help install
35.3. How do I build Vim from the sources on a MS-Windows system?
For a MS-Windows system, Vim can be built using either the Visual C++
compiler or the Borland C++ compiler or the Ming GCC compiler or the cygwin
gcc compiler. Follow these steps to build Vim from the sources for
MS-Windows:
- Download the source (vim##src.zip), runtime (vim##rt.zip) and the extra
(vim-##-extra.tar.gz) archives from the ftp://ftp.vim.org/pub/vim/pc
directory.
- Extract the archives into a directorry (for example, c:\vimsrc)
- Depending on the installed compiler,, you can use the corresponding
makefile to build the Vim sources. For Visual C++ use the Make_mvc.mak
makefile, for borland C++ use the Make_bc5.mak makefile, for ming GCC use
the Make_ming.mak makefile, for cygwin gcc use the Make_cyg.mak makefile.
Depending on whether you want to build the GUI version of Vim or the
console version of Vim, you have to pass different arguments to the
makefiles. After successfully building the sources, you can copy the
vim.exe or gvim.exe file to the desired directory along with the files from
the runtime archive.
You can visit the following site for extensive information about building
Vim on a MS-Windows system using the various compilers:
http://mywebpage.netscape.com/SharpPeople/vim/howto/index.html
For more information, read
:help install
35.4. The Vim help, syntax, indent files are missing from my Vim
installation. How do I install these files?
The Vim help, syntax, indent and other runtime files are part of the Vim
runtime package. You need to download and install the Vim runtime package.
For example, for MS-Windows, the name of the Vim 6.1 runtime package is
vim61rt.zip.
For more information, read
:help install
35.5. I have built Vim from the source and installed the Vim package using
"make install". Do I need to keep the Vim source directory?
No. Once you have built and installed Vim in some directory other than the
original source directory (for example, /usr/bin or /usr/local/bin), then
you can remove the source directory.
35.6. How do I determine the Vim features which are enabled at compile
time?
You can use the ":version" command to determine the Vim features that are
enabled at compile time. The features that are enabled will be prefixed
with a "+". The features that are not enabled will be prefixed with a "-".
If you want to test for a feature in a script, you can use the has()
function:
if has("menu")
" Set up some menus
endif
For more information, read
:help :version
:help +feature-list
:help has()
35.7. Can I build Vim without the GUI support?
Yes. You can build Vim by optionally enabling/disabling many of the
features including GUI.
For more information, read
:help install
35.8. When building Vim on a Unix system, I am getting "undefined reference
to term_set_winsize' error. How do I resolve this error?
You will get this error when the build process is not able to locate the
termlib, termcap or ncurses library. You have to install the ncurses-dev
package to resolve this error.
35.9. Vim configure keeps complaining about the lack of gtk-config while
trying to use GTK 2.03. This is correct, since in GTK 2 they moved to
using the generic pkg-config. I can get pkg-config to list the
various includes and libs for gtk, but for some reason the configure
script still isn't picking this up.
Use the following shell script named gtk-config:
#!/bin/sh
pkg-config gtk+-2.0 $1 $2
=============================================================================
SECTION 36 - VARIOUS
36.1. How do I edit binary files with Vim?
You can set the following options to edit binary files in Vim:
:set binary
:set display=uhex
You can also use the "-b" command-line option to edit a binary file:
$ vim -b <binary_file_name>
You can also use the xxd utility (part of the Vim distribution) to edit
binary files.
For more information, read
:help 23.4
:help edit-binary
:help hex-editing
:help -b
:help 'binary'
:help 'endofline'
:help 'display'
36.2. How do I disable the visual error flash and the error beep?
You can disable both the visual error flash and the error beep using the
following command:
:set visualbell t_vb=
For more information, read
:help 'visualbell'
:help 'errorbells'
:help t_vb
36.3. How do I display the ascii value of a character displayed in a
buffer?
You can use the 'ga' command to display the ascii value of a displayed
character.
For more information, read
:help ga
:help :ascii
36.4. Can I use zero as a count for a Vim command?
You cannot use zero as a count for a Vim command, as "0" is a command on
its own, moving to the first column of the line.
For more information, read
:help 0
:help count
36.5. How do I disable the Vim welcome screen?
You can disable the Vim welcome screen, by adding the 'I' flag to the
'shortmess' option:
:set shortmess+=I
For more information, read
:help :intro
:help 'shortmess'
36.6. How do I avoid the "hit enter to continue" prompt?
Vim will prompt you with the "hit enter to continue" prompt, if there are
some messages on the screen for you to read and the screen is about to be
redrawn. You can add the 'T' flag to the 'shortmess' option to truncate
all messages. This will help in avoiding the hit-enter prompt:
:set shortmess+=T
You can also increase the command height by setting the 'cmdheight' option:
:set cmdheight=2
For more information, read
:help hit-enter
:help avoid-hit-enter
:help 'shortmess'
:help 'cmdheight'
36.7. How do I invoke Vim from command line to run a group of commands on a
group of files?
There are several ways to invoke Vim from command line to run a group of
commands on a group of files. You can use a set of "-c" command line
options to specify a group of commands:
$ vim -c "<ex_command_1>" -c "<ex_command_2>" *.txt
Each of the ex-command specified with the "-c" command line option is
executed one by one sequentially. You can also use a single "-c" command
line option and the "|" character to separate the ex commands:
$ vim -c "<ex_command_1> | <ex_command_2>" *.txt
In the above command, if an ex command fails, then all the remaining ex
commands will not be executed.
For example, to replace "ABC" with "DEF" in a file from the command-line,
you can use the following command:
$ vim -c "%s/ABC/DEF/ge | update" myfile.txt
To replace "ABC" with "DEF" in multiple files from the command-line,
you can use the following command:
$ vim -c "argdo %s/ABC/DEF/ge | update" *.txt
You can store the group of commands into a file and use the "-s" command
line option to run the commands on a set of files. For example, if the
group of commands are stored in the file mycmds.txt, then you can use the
following command:
$ vim -s mycmds.txt *.pl
For more information, read
:help -c
:help -s
36.8. How do I use a normal mode command from insert mode without leaving
the insert mode?
You can use a normal command from insert mode, without leaving the insert
mode, by first pressing the CTRL-O key and then follow that with a single
normal mode command.
To execute more than one normal mode command, press the CTRL-L key,
followed by any number of normal mode commands and then press <Esc> to get
back to the insert mode.
For more information, read
:help i_CTRL-O
:help i_CTRL-L
=============================================================================
SECTION 37 - UNICODE
Author: Tony Mechelynck <antoine.mechelynck AT belgacom.net>
37.1. Is it possible to create Unicode files using Vim?
Yes. It may be more or less complicated depending on the keyboard and fonts
available to you, but it is always possible to encode any possible Unicode
codepoint (and some illegal ones) into a file. To create a Unicode file
using Vim, you should have compiled Vim with the "+multi_byte" compile-time
option. You can get more information about Unicode from the following
sites:
http://www.unicode.org
http://www.cl.cam.ac.uk/~mgk25/unicode.html
For more information, read
:help multibyte
:help usr_45.txt
37.2. Which Vim settings are particularly important for editing Unicode
files?
The most important are the various "encoding" options, i.e., 'encoding',
'fileencoding', 'fileencodings' and 'termencoding'. The boolean option
'bomb' is also significant.
For more information, read
:help 'encoding'
:help 'fileencoding'
:help 'fileencodings'
:help 'termencoding'
:help 'bomb'
37.3. What is the 'encoding' option?
Basically, the 'encoding' option defines how Vim will represent your data
internally. However, all Unicode encodings are represented internally as
utf-8 and converted (if necessary) when reading and writing.
For more information, read
:help 'encoding'
37.4. How does Vim name the various Unicode encodings?
Utf-8 is called utf-8 or utf8; utf-16 is called ucs-2 or ucs2; utf-32 is
called ucs-4 or ucs4. Also, you may specify endianness (except for utf-8
which does not vary for endianness) by appending le for little-endian or be
for big-endian. If you create a file with an encoding of ucs-2 or ucs-4
without specifying endianness, Vim will use what is typical of your
machine.
For more information, read
:help encoding-names
:help encoding-values
:help encoding-table
37.5. How does Vim specify the presence or absence of a byte-order mark?
When reading a file, if the 'fileencodings' option includes "ucs-bom", Vim
will check for a byte-order mark. When writing a file, if the 'bomb' option
is set, Vim will write a byte-order mark on files whose encoding warrants
it.
For more information, read
:help 'fileencodings'
:help 'bomb'
37.6. What is the 'fileencoding' option?
The 'fileencoding' option defines the particular encoding which Vim will
use to write a file. If empty, then the value of the 'encoding' option is
the default.
For more information, read
:help 'fileencoding'
37.7. What is the 'fileencodings' option?
The 'fileencodings' option defines the heuristics used by Vim when opening
an existing file. It is a comma separated list of encodings. A special
name, "ucs-bom" is used to indicate that Vim should check for the presence
of a byte-order mark; however, it will not be recognised if it comes after
"utf-8". Normally, "ucs-bom" (if present) should be first in the list.
When Vim opens a file, it checks it against the encodings listed in
'fileencodings'. The first one that matches is used. If there is no match,
then Vim sets 'fileencoding' to the null string, i.e., the value of
'encoding' will be used.
For more information, read
:help 'fileencodings'
:help 'encoding'
37.8. What is the 'termencoding' option?
The 'termencoding' option defines how your keyboard encodes the data you
type. If empty, Vim assumes that it has the same value as 'encoding'.
Usually it should be set to something that matches your locale.
For more information, read
:help 'termencoding'
:help locale
37.9. What is the 'bomb' option?
When reading a file with "ucs-bom" present in the 'fileencodings' option,
Vim will set the 'bomb' option on or off depending on the presence or
absence of a byte-order mark at the start of the file. When writing, Vim
will write a byte-order mark if the 'bomb' option is set. You may set or
unset it manually do make Vim write, or not write, the b.o.m.
For more information, read
:help 'bomb'
37.10. Where can I find an example of a typical use of all these options?
There is a "tip", with explains them in different words with an example, at
http://vim.sourceforge.net/tip_view.php?tip_id=246 .
37.11. How can I insert Unicode characters into a file using Vim?
Several methods are available:
- Characters present on your keyboard can be typed in the usual way, even
those which require a "dead-key" prefix, like (for instance) the
circumflex on French keyboards.
- Characters for which a digraph is deefined can be typed as two characters
prefixed by <Ctrl-K>.
- If you have set the 'digraph' optionn, you can enter the characters for
which a digrph is defined as <char1><BS><char2>.
- Any character can be entered by usinng a <Ctrl-V> prefix (or <Ctrl-Q> if
<Ctrl-V> is remapped to paste from the clipboard).
For more information, read
:help digraphs
:help 'digraph'
:help i_CTRL-V_digit
37.12. How can I know which digraphs are defined and for which characters?
First set the 'encoding' option properly (for instance, to utf-8), then use
the :digraphs command to list the currently defined digraphs.
For more information, read
:help :digraphs
:help 'encoding'
