#vim: How to remap the Esc key?

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 Esc, and disable the Esc key. (thanks to 00Davo〔☛ Programer Hand Health: vi Esc Key Syndrome#comment-1426377905〕)

if you have a special keyboard (such as the ergodox 〔☛ 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

and, get vimrc-mode to make your vimrc pretty:

(autoload 'vimrc-mode "vimrc-mode" "loads vimrc-mode" "INTERACTIVE")

(when (fboundp 'vimrc-mode)
  (add-to-list 'auto-mode-alist '(".vim\\(rc\\)?$" . vimrc-mode))

and, an interesting thing about vimrc syntax is that its comment starts with "

that's right, a single double quote at the beginning of line. I used another quote at the end of line just to make it familiar and save myself trouble of creating another css to deal with vimrc mode.
