I’m just about to install a crontab entry, and boom - I end up in the weird default editor. The one I never quite understood.
ESC? Nothing happens.
CTRL + C? No.
ESC ESC ESC? Nope. I’m stuck.
Not again. With my head down in shame, I’m resorting to opening another session just to
killall vim to get on with my day.
Sound familiar? I don’t know about you, but I’ve been there. Until I decided to spend 10 minutes learning the very basics of Vim.
This post is your survival guide to the editor Vim. It’s not advanced, but enough to get you started and hopefully spark your interest in learning more.
Vim is shipped by default with many operating systems (including most Linux distributions and Mac OS X), so I suggest you take a proactive approach to learning it. Just launch a terminal and type ‘vim’ to get started.
With some learning, Vim can be more powerful than many graphical IDEs. And it certainly doesn’t eat hundreds of megs of memory just to view an empty file (looking at you, Eclipse).
Some commands in this guide start with a colon
: pressing it will display the command prompt where the subsequent command is written.
Commands without a colon are more like hotkeys - they can be used in the Vim default mode (which is the mode Vim starts in).
Commands written in CAPITAL LETTERS are specific keys: for example, ESC means the escape key on your keyboard.
All commands in Vim are case-sensitive.
To quit, discarding any changes you might have made:
Memorize: quit dammit!
To quit, saving any changes you’ve made:
Memorize: write to disk and quit
Navigating the editor
To move around the currently open file, use your arrow keys.

Cut, copy and paste
To copy the current selection into the buffer (think of it as a clipboard):
To cut the current selection:
To copy the current line into the buffer:
Memorize: yank yank
To copy 3 lines including the current line into the buffer:
To cut the current line and place it into the buffer:
Memorize: delete delete
To cut 5 lines including the current line:
To paste the buffer before the current line:
Note: Uppercase P
To paste the buffer after the current line:
Undo and redo
To undo the last change:
Memorize: uh-oh :)
To redo the last change you just undid:
CTRL + R
To see the number of changes:
To undo the last two changes:
The Vim multi-level undo tree is very powerful. Read more about it here.
To open the file
index.html instead of the current one:
To save the file you’re currently editing:
Memorize: write to disk
To save the file with a different name, here changes.txt (ie. Save As):

To search and replace, but prompt before replacing:
Syntax highlighting and Indentation

Working with multiple files
server.py in a new tab:
Memorize: tab edit
To move to the next tab on the right:
Memorize: tab next
To move to the previous tab on the left:
Memorize: tab previous
To close a tab, move to it and use
:wq as you would normally.
templates/base.html in a vertical split screen:
Memorize: vertical split
shared.js in a horizontal split screen:
Memorize: the ‘default’ horizontal split
To move between split screens:
CTRL + W + ARROW KEYS
To close a split screen, move to it and use
:wq as you would normally.
Configuring Vim: the .vimrc
Many of the commands you use to change how Vim looks and behaves can be made default by placing them in the
.vimrc. This is the Vim configuration file, and it lives in your home directory.
For example, placing this in
~/.vimrc will enable syntax highlighting and autoindentation by default:
syntax on set autoindent
