My question comes from this two commands I added on my _vimrc file:

nnoremap <C-[> :set columns+=1<CR>
nnoremap <C-]> :set lines+=1<CR>

As is known, it will resize your gvim (I am using gvim on windows) with one more column when you hit Ctrl-[, and one more line when you hit Ctrl-]. That is really cool since you can achieve that resizement as though you are using your mouse.

I wonder if I can map those two command with only one key to make it more comfortable.

  • Beware that <C-[> is the same as <ESC>. It's a really bad idea to mess with that. You might want to choose a different key combination. – lcd047 Jul 8 '15 at 11:20
  • @lcd047 oh yeah that is right. thanks for that – Alex Jul 8 '15 at 11:26

You can do this with | (on windows, in the _vimrc file, so you have to replace it with <bar>).

e.g.

" unix
nnoremap <C-[> :set columns+=1 | lines+=1<CR> 
" windows
nnoremap <C-[> :set columns+=1 <bar> lines+=1<CR> 

See the documentation : :help :bar

    the | is good, but that doesn't work in _vimrc file. It would be ok if you replace it with <bar> (as the answer in stackoverflow suggest) – Alex Jul 8 '15 at 11:08
  • Why doesn't | work in Windows? – Martin Tournoij Jul 8 '15 at 12:45
  • | doesn't work, you either need \| or <bar>. – romainl Jul 8 '15 at 12:48
  • on the documentation, there is no mention of this incompatibility. But as @michaelmichael said on he's answer : NB: You may find that your ~/.vimrc doesn't support mapping |, or \|. In these cases, try using <bar> instead. – nobe4 Jul 8 '15 at 12:49

I would recommend you to use for example <C-P>, since <C-[> is the same as <Esc> and <C-]> is used to jump to a definition of the keyword under the cursor.

You can just do this:

nnoremap <C-P> <Esc>:set columns+=1 lines+=1<CR>

The another way is to use the command separator |, but you have to escape it or use <Bar> to use it as an argument for the nnoremap command, otherwise it would be recognized as command separator in the vimrc file, not in the mapping.

nnoremap <C-P> <Esc>:set columns+=1 \| set lines+=1<CR>

So when you press <C-P>, this command is executed:

set columns+=1 | set lines+=1
  • But also note that the <C-p> is used to autocomplete text in vim, which is a built-in utility. I haved used a <M-p> instead. But anyway, the<Esc> in front of the command is a very good addition. – Alex Jul 8 '15 at 13:42
  • @Alex You have mapped it only in normal mode. So you can still use <C-P> in insert mode to autocomplete text. – MichalH Jul 8 '15 at 13:51
  • oh yes you are right. – Alex Jul 8 '15 at 23:17
