How to make vim use some other key to do Escape?
Create a file at ~/.vimrc, and put the following
"make jj do esc" inoremap jj <Esc> "make esc do nothing" inoremap <Esc> <Nop>
this will make 【jj】 do Escape, and disable the Escape key. (thanks to 00Davo[see Programer Hand Health: vi Esc Key Syndrome#comment-1426377905])
if you have a special keyboard (such as the ergodox [see Ergonomic Keyboards] ) where the {Home, End} keys are right under your thumbs, then you can make them do command mode and insert mode, like this:
"make home key do esc when in insertion mode" :imap <Home> <Esc> "make end key go to insertion mode, when in command mode" :map <End> i "turn on line numbering" :set number
