Exit vim more quickly

ZZ in normal mode saves the current file if modified and exits or closes the current window/tab (same as :x but not :wq which writes the file even if it hasn't been modified).

To exit unconditionally after having written all the modified files in all windows, tabs and hidden buffers, you need :xa (it still won't exit if some files can't be written for a reason or another)

To exit unconditionally without changing anything: ZQ (same as :q!).

:x is one key less than :wq

Two keystrokes only!

Ctrl + s to save,

ctrl + d to save and exit,

ctrl + q to exit discarding changes.

1st. Put this to your ~/.bashrc

bind -r '\C-s'
stty -ixon

2nd. Place this to your ~/.vimrc

inoremap <C-s> <esc>:w<cr>                 " save files
nnoremap <C-s> :w<cr>
inoremap <C-d> <esc>:wq!<cr>               " save and exit
nnoremap <C-d> :wq!<cr>
inoremap <C-q> <esc>:qa!<cr>               " quit discarding changes
nnoremap <C-q> :qa!<cr>

3rd. Restart vim

Get more productive day !

Create a custom mapping for frequenly used tasks. If you quit vim often, create a mapping with few key strokes, e.g.

nnoremap <leader><leader> :xa<cr>

If the <leader> is set to comma using let mapleader = "," hitting comma twice is a quick way of quitting vim and saving your changes. If you want to save one more key stroke when you are in insert mode, also create a corresponding insert mode mapping:

inoremap <leader><leader> <esc>:xa<cr>

But beware, this might accidentally quite vim when you hit the <leader twice.

How about just Q for 'Quit'?

That'll only require one shifted keystroke (i.e. Shift and Q). It's also a key combination that I rarely hit by accident.

By default, vim maps Q to switch to "Ex" mode. If you find "Ex" mode as useless (or annoying) as I do, then you won't miss its default function at all.

Here is what I have in my .vimrc file:

" allow quit via single keypress (Q)
map Q :qa<CR>

If you have unsaved buffers, it'll prompt you before exiting.

Here is a cheat sheet for VIM

Cheat-sheet-for-VIM

To quit the vi editor without saving any changes you've made:

If you are currently in insert or append mode, press Esc. 

Press  :  (colon). The cursor should reappear at the lower left corner of the screen beside a colon prompt. 

Enter the following:
  q!
This will quit the editor, and all changes you have made to the document will be lost.

Closing and Saving Files

When you edit a file in vi, you are actually editing a copy of the file rather than the original. The following sections describe methods you might use when closing a file, quitting vi, or both.
Quitting and Saving a File

The command ZZ (notice that it is in uppercase) will allow you to quit vi and save the edits made to a file. You will then return to a Unix prompt. Note that you can also use the following commands:

:w  to save your file but not quit vi (this is good to do periodically in
    case of machine crash!).
:q  to quit if you haven't made any edits.
:wq to quit and save edits (basically the same as ZZ).
Quitting without Saving Edits

Sometimes, when you create a mess (when you first start using vi this is easy to do!) you may wish to erase all edits made to the file and either start over or quit. To do this, you can choose from the following two commands:

:e! reads the original file back in so that you can start over.
:q! wipes out all edits and allows you to exit from vi.

My simple and convenient solution for quit and save from vim - is:

Ctrl + X shortcut.

Jut add this code to .vimrc file:

"Fast quit and save from normal and insert mode
:map <C-X> <ESC>:x<CR>
:imap <C-X> <ESC>:x<CR>

Try

nno : ;
nno ; :
vno : ;
vno ; :

If you use fFtT this will take some getting used to, but now quitting's just ;x to save if needed, ;q to not save. Plus, everything else gets quicker too.
