1 Introduction
Vim is not just an editor. It can be an IDE if used at its best. I have found
it more convenient to use than any other word processing tool i have used.
With proper knowledge of the countless features provided by vim, one can be
much more efficient in whatever editing job, and programming in my case.
Every time i wished for a feature, i found it there in vim. I didnt allow
myself to do anything the stupid way, and always figured out a better way
to do the same thing. Thats how i have got a decent expertise on vim. With
this tutorial i wish to give you a feel of what all is possible with vim, and
show you a direction to learn more.
Before i proceed, i would like to ask you a question. Suppose you have
got a file with about 50 lines only, and you have to make few changes to the
file. Lets assume that you are asked to add 10 to every number present in the
file. Lets assume that there are only 25 numbers in the file and rest is text.
Would you start doing it the stupid way or search for a efficient way to do
it ? Most of the times one will think that its just 25 numbers, and without
thinking about a better way to do it, starts editing it right away. Or even
if one does want to do it a better way he doesnt do it thinking that figuring
out the better way will take much more time than doing it the obvious way.
But what we always ignore is that its not just this time. We do it many
times, and thats why it makes sense to go for the better way to do it, even
if it takes more time at first time.
So next time when the thought  its just this much comes to your mind,
just remember that  its not just this time , and the choice is yours.
If we go by Brook s words  The tool that save the most labor in a pro-
gramming project is probably a text-editing system [The Mythical Man-
Month, proposition 12.10], then we should probably work on our editing
skills more than our programming skills.
In this tutorial I assume the reader to have a basic knowledge of vim.
Basic features like editing, movement, searching, replacing, opening, saving
1
etc are not covered in this tutorial. I d recommend going throughvimtutor
for basic understanding of vim.
Remember :  if its just this much, its not just this time
2 Shortcuts
easily and efficiently execute more complex commands and statements.
2.1 Map
map is used to change the meaning of sequence of keystrokes, usually to
perform a job using easier keystrokes, which would otherwise need more
complex keystrokes. Sometimes simple but frequently used keystrokes are
also mapped.
o map can be used for
- changing meaning of typed keys
- execute a function on certain keystrokes
o mapping can be set for one or more of following modes using the com-
mands written against them.
normal nmap,map
visual vmap,map
insert imap,map!
command-line cmap,map!
operator-pending omap,map
o two forms of map
-map
-noremap
to avoid recursion
ounmap
remove the mapping
o examples
map :w
imap n
see:help mapping

2.2 Abbreviations
change the meaning of a word. Can be used in insert , replace and command
line mode.
Abbreviations can be used for
- typos correction
iabtihs this
- making abbreviations

3 Windows, Buffers and Tabs
Buffer is the vim s copy of the file you are editing. Window is a viewport
onto a buffer. Tab holds windows.
3.1 Window Management
:splitor C-W s
split the active buffer horizontally
:vsplitor C-W v
split the active buffer vertically
:newor C-W n / :vnew
open a new buffer (empty)
other commands
all other commands work as they use to for single window
therefore:wfor saving and:qfor quitting
-o argument to vim
start vim with multiple windows each opening the files supplied
to -o
Navigation through windows
C-W w / C-W W / C-W C-W
- iterate through the windows (go to next/previous window)
see:help windows
3
3.2 Buffer Management
:e
open new buffer (of the supplied)
:ls
show current buffers
:b
switch to buffer
:bdelete
unload buffer
:bwipeout
unload buffer and deletes it
see:help buffers
3.3 Tabs Management
Tabs are available only in version 7 or later. Tabs provide a traditional(like
in other GUIs) tabbed view over the vim windows and buffers. If mouse is
enabled in vim, tabs can be opened, closed or selected using mouse clicks.
Tabs shares registers, and therfor allow deleted/yanked text from one tab to
be pasted on others. Also undo history of every tab is maintained separately,
which allows switching between the tabs without loosing the changes history.
This is not possible in buffers. Also buffers does not allow switching between
buffers without saving the current buffer, which is now possible between tabs.
:tabe
Open in new tab. Opens empty tab if no file is supplied
tabs
List opened tabs along with windows/buffers they contain
tabc
Close the active tab
tabnandtabp
Go to next(on tabn) or pervious(on tabp) tab
and also works
CTRL-W gf
Open the filename under cursor in new tab
see:help tabpage

4 Visual Mode
Visual Mode provides us flexible and easy way to select text and execute
command (operator) on it.
see:help Visual
4.1 Visual Block
Rectangular block of selected text
invocation key : CTRL-V
4.2 Visual Line
Text is selected line-wise
invocation key : V (ie Shift-v)
4.3 Visual (Char)
Text is selected char-wise
invocation key : v
4.4 Role of Mouse in visual mode
setting mouse to  n or  a allows selecting visual area using mouse
click and mouse drags
4.5 Select Mode
select mode is similar to selection mode in Microsoft Windows Notepad. Typ-
ing any printable key replaces the selected text with the key.
Invocation keys : gh / gV / gH / G CTRL-H
see:help Select
4.6 Important keys
gv select previous visual area again
CTRL-G switch between Visual and Select
< shift selected text toward left
> shift selected text toward right
5
d or y Delete or Yank selected text
I or A Insert or Append text in all lines (visual block only)
5 Advanced Navigation Techniques
5.1 Change-list jumps
helps in iterating through recent cursor positions (where changes were made)
g; go to the previous position of cursor in change list
g, go to the next position of cursor in change list
see:help changelist
5.2 Marks
Marks allow us to label cursor position. It can be used to label import
locations in file for easy navigation.
m set label to current cursor position
 go to position labeled
see:help mark-motions
5.3 Tags
Tags are also labels used for jumping through them. Tags are read from the
tags file.
Important keys
:tag position the cursor on tag position
CTRL-] position the cursor on tag under the cursor
CTRL-T go back after the previous jumps
:ptag show tag in the preview window (see :help preview-window)
CTRL-W } show tag under cursor in preview window
CTRL-W z close preview window (opened by above 2 commands)
ctags*.cpp *.h
6
generates tags using GNU/Linux commandctags(seeman ctags)
this command will create a file named tags with all tags found in
files supplied
see:help tags
5.4 Mouse
enable use of mouse in vim, for scrolling or visual selection
:set mouse=n/v/i/c/h/a/r/A
enable mouse for the corresponding mode (normal/visual/insert/etc..)
eg :
:set mouse=nvi enables mouse in normal,visual and insert mode
:set mouse=a enables mouse in all modes
see:help mouse
* although mouse and arrow keys can be helpful sometimes, but vim users
are advised not to use mouse or arrow keys. It helps gain more efficiency
over the keyboard.
6 Repeating commands
Repeating capability of vim allows us to execute a command or set of keystrokes
multiple times without any pain.
6.1 Repeat Last Action
.(dot) Repeat last change
@: Repeat last command
see:help single-repeat
6.2 Recording
Record keystrokes and playing them again.
7
q start recording characters into register
q stop recording
@ play keystrokes recorded into register
@@ repeat last recording
see:help record
6.3 Select and execute
Run command on selected lines only
:g//
runs command on all lines in where
matches
g! or v works on NOT of above. That is execute where
doesnt match.
see:help multi-repeat
7 Registers
Registers are used to store the deleted, yanked text and recorded statements.
Registers are named single char from the list a-zA-Z0-9.
a-z named registers. These are used used only when explicitly specified
A-Z appends to the lowercase register
0-9 filled with deleted lines. Shifted on new entries.
(underscore) black hole register. Use when u don t want to change the value of any register.
:reg shows contents of all registers
action is stored in register . can be yank or delete.
paste the contents of register .
see:help registers
8 Folds
folds are useful for providing readable and easyily navigable view of the file.
8
8.1 Fold Methods
decides the criteria for creating folds.
foldmethod can be set to
manual manually created
indent based on indentation. Useful for python or other indented codes
marker based on foldmarker
8.2 Folding Commands
zf create fold
zo/zO open fold
zc/zC close fold
:set foldmethod=manual/indent/marker
:set foldmarker=, or <,>
see:help Folding
9 Functions
Sometimes what we want to do cannot be implemented with commands or
keystrokes. We need to define our functions and call them. Ex :
function! MyCompile()
let choice = confirm(Compile method , \&make\\n\&g++ \%.cpp )
if choice == 1
exec :make
elseif choice == 2
exec !g++ \%.cpp
else
endif
endfunction
see:help function
10 Compiling and Executing
vim helps in edit-compile-edit cycle with its compiling and executing features
called quickfix commands.
9
:makeruns makeprg
makeprg is set to make by default but one can change it
to anything
eg:set makeprg=g++\ main.cpp or:set makeprg=g++\ %
:cnext show next compilation error
:cprevious show previous compilation error
:copen open errors window
:cclose close errors window
Now you can use the following mappings -
:map :mak
:map :cn
:map :cp
:map :!./a.out
and compilation and execution become becomes as easy as single
key press. And more importantly we are able to iterate through
errors more easily, and fix them without any pain.
see:help quickfix
11 Filters
Filter allows us to run an external command as filter on the text specified
by range or visual selection. The selected text is changed inplace.

see:help complex-change
12 Plugins
Vim allows to use plugin scripts. Plugins are loaded everytime vim starts.
plugins can be placed in  runtimepath/plugins/ ( generally .vim/plugins/ ).
10
vim.org hosts a huge repository of vim plugin scripts at http://vim.org/srcipts/.
A few useful plugins scripts are -
taglist (source code browser) [http://www.vim.org/scripts/script.php?script id=273]
minibufexlporer [http://www.vim.org/scripts/script.php?script id=159]
vimspell [http://www.vim.org/scripts/script.php?script id=465]
template file loader [http://www.vim.org/scripts/script.php?script id=198]
see:help plugin
13 Misc
This section lists other misc features
13.1 Sessions
Sessions allows you to save your buffers, windows, tabs and settings of cur-
rent vim session to a file for restoring at later time.
:mksession save session to
$ vim -S restore session from
see:help session
13.2 Undo Branching
Vim has simple undo (key: u) and redo (key: Ctrl-R) functionality. Start-
ing from version 7.0 vim has also added undo branching. Undo branching
happens when you undo a few levels and make new changes. These branches
are not reachable with simple undo/redo functionalities. Undo branching
support of vim makes these branches reachable.
:undol Show the Undo Branches ( the leaves of these branches )
:earlier Go to older state. Time or steps can be specified.
:later Go to newer state. Time or steps can be specified.
see:help undo-branches
11
13.3 Spell Checking
Spell checking can be enabled using the command:set spell spelllang=en_us.
We also set the language to use. US English in this case. Spell checking is
turned off using:set nospell. Spell checking is also a feature added in
version 7.0.
Important keys -
]sor[s Move to next (]s) or previous ([s) misspelled word
zg Add word under cursor as good word
z= Suggest corrections for the word under cursor
see:help spell
13.4 Highlights
Set the foreground and background color and style of distinguished text
:hi
 show current highlight settings
:hi Comment cterm=bold ctermfg=white ctermbg=black
 changes the hilighting settings for Comments
see:help hi
13.5 Autocommand
specify commands to be executed automatically for when reading or writing
a file , entering or leaving buffer etc. (Goes in .vimrc)
example :
autocmd BufRead *.c,*.h,*.cpp,*.cc setlocal cindent
see:help autocommand
13.6 Incrementing and Decrementing integers
CTRL-A increment number under cursor
CTRL-X decrement number under cursor
12
13.7 Numerical Arguments
Most of the vim commands take numerical arguments. These arguments are
set by typing the number before typing the command.
Eg: 8dd , 2K , 7yy, etc..
13.8 Useful settings
better visualization of tabset :set list,set listchars=tab:. ,trail:.s
in place search :set incsearch
keep cursor away from top/bottom :set scrolloff= (4 is good)
always show a status bar :set laststatus=2
13.9 Others
ga Show ASCII value of character under cursor
gf Open file under cursor
g Count words in the file
<< Shift lines to left
>> Shift lines to right
:!cmd Run command on terminal
vimdiff show difference between files (shell command)

14.3 Emacs
Another equally good editor. GNU & RMS product. Lisp based.
Emacs vs Vim
its your call.
But let the reason be more than geekyness and blind support
of GNU.
Bottom line : If unlike me you find Ctrl-X Alt-Y Shift-Z natu-
ral way of editing, there is no reason you shouldnt use it.
Emacs Tutorial
Ctrl-h t emacs turorial. Good enough to get you started.
Ctrl-x u or Ctrl-/ undo
Ctrl-s search
Ctrl-h c show help on
Ctrl-h k show more help on
Ctrl-h f describe a function
Ctrl-h a show command apropos
14
Ctrl-x 1 close all windows but active
Alt-x execute a command by its name
Ctrl-g quit current command. Return to normal mode.
Ctrl-x Ctrl-c quit emacs. Dont enter emacs without remembering it.
