💡 Motivation

A lot of people have been mapping jk or kj or kk to ESC in order to escape insert mode quickly. However, when we press the first key in these mappings, Vim/Nvim will wait for timeoutlen milliseconds before writing this char to buffer. The apparent lag caused by this behaviour is annoying.

Better-escape.vim is created to help Vim/Nvim users escape insert mode quickly using their customized key combinations, without experiencing the lag.

🚀 Quickstart

Requirements

Neovim: 0.4.4 and above
Vim: 8.0 and above (not tested on Vim 7.4)

Install

Use your favorite plugin manager to install it:

packer.nvim: use {'jdhao/better-escape.vim', event = 'InsertEnter'}
vim-plug: Plug 'jdhao/better-escape.vim'
dein: call dein#add('jdhao/better-escape.vim')
vim-packager: call packager#add('jdhao/better-escape.vim')
minpac: call minpac#add('jdhao/better-escape.vim')

How to use?

This plugin works out of the box. The default shortcut for escaping insert mode is jk, that is, pressing j first, then pressing k quickly, you will leave insert mode.

🔧 Configuration

How to change shortcut

If you want to use other shortcuts, you can customize via option g:better_escape_shortcut:

" use jj to escape insert mode.
let g:better_escape_shortcut = 'jj'

Adjust time interval threshold

By default, the time interval threshold between pressing j and k is 150 ms. That is, if the time interval between pressing k and j is above the threshold, jk will be inserted literally. Otherwise, we assume you want to leave insert mode. The threshold can be customized via option g:better_escape_interval:

" set time interval to 200 ms
let g:better_escape_interval = 200

Using multiple shortcuts?

Some people may prefer to use multiple shortcuts. This is also supported:

# non-ASCII shortcuts are also supported for non-English keyboard.
let g:better_escape_shortcut = ['jk', 'jj', 'kj', 'лл']

Debug and choose suitable interval

Sometimes, you may wonder why the given escape shortcut does not work as intended. Maybe it is because you have not pressed the two keys fast enough. To get the interval between key presses and help you to set a reasonable interval, use the option g:better_escape_debug:

" enable debug (some message will be shown)
let g:better_escape_debug = 1

Then run command :messages to check the debug log.
