remap_keys.md

In Vim, the <ESC> and <CTRL> keys are hard to reach, but used a lot.

New way to get out Insert mode

Change the <ESC> key to jk. It allows efficient escape from Insert mode, as your fingers should already be on j and k keyboard keys.

In ~/.vimrc:

inoremap jk <ESC>

Remap <CAPS LOCK> to <CTRL>

The <CTRL> key is hard to reach and the <CAPS LOCK> key is useless. We have to remap at the system level. For Ubuntu 14.04, modify the /etc/default/keyboard file with replacing:

XKBOPTIONS=“”

with:

XKBOPTIONS=“ctrl:nocaps”

We then have to restart the computer.
