How do you exit vimdiff mode in vim, specifically, for Fugitive?

Question

I am using vim with the fugitive extension. It has a :Gdiff command which brings you into vimdiff mode, but what is the right/quick way to close/quit vimdiff mode?

I.e.,

Answer 1

Method 1:

• open a compare by:

:windo diffthis

• close it by:

:windo diffoff

Method 2:

I recommend just using the most simple command: :q

when you want to do it quickly, add the mapping:

" Set mapleader
let mapleader = ","
let g:mapleader = ","

and

" Quickly close the current window
nnoremap q :q

It works well for me. Exit vimdiff just by ,q, because normally your cursor in the old file.
