idea: extends the plugin to support other similar insert mode mappings

[jdhao]

For example, if we use the following mapping:

inoremap ;; <Esc>A;

We also experience lagging when we press ; in insert mode. So we can also do the same thing. We check if the time interval between pressing the two chars is below the time threshold. If that is the case, we execute its original intended mapping, otherwise, we just insert the character literally.

Here is a crude implementation:

let g:my_map = {";;": "\<Esc>mmA;\<Esc>`ma"}

let g:char_press_time = {}

inoremap <expr> ; My_map()

augroup log_press_time
  autocmd!
  autocmd InsertCharPre * call Log_char()
augroup END

function! Log_char() abort
  if v:char == ';'
    let g:char_press_time[';'] = reltime()
  endif
endfunction

function! My_map() abort
  let idx = col('.')
  let pre_idx = idx-1
  let pre_char = getline('.')[pre_idx-1]

  if pre_char == ';'
    let interval = reltimefloat(reltime(g:char_press_time[";"])) * 1000
    echomsg "interval:" interval

    if interval < 200
      return "\b" . g:my_map[";;"]
    else
      return ";"
    endif
  else
    return ";"
  endif

endfunction

In order to avoid the step left after exiting insert mode with ESC, I now do

 inoremap <silent> kj <C-O>:stopinsert<CR>

What's the best way to use your plugin to map kj this way rather than to ESC? Thanks
