As you all may know with 'o' or 'O' you can insert a new line after/before the current line. But both commands enter the insert mode, which may sometimes not what you want. I put this in my vimrc-file to insert a new-line after the current line by pressing Enter (Shift-Enter for inserting a line before the current line):

nmap <S-Enter> O<Esc>
nmap <CR> o<Esc>

If you want to stay in the line where you have been before use the following maps:

nmap <S-Enter> O<Esc>j
nmap <CR> o<Esc>k

It's also a nice idea to map something like

nnoremap <C-J> a<CR><Esc>k$

because it's the opposite of Shift-J. A more sophisticated solution would be

nnoremap <C-J> ciW<CR><Esc>:if match( @", "^\\s*$") < 0<Bar>exec "norm P-$diw+"<Bar>endif<CR>

For whatever reason, I was unable to get the suggest mapping with <S-Enter> and <CR> to work properly (both ended up inserting below). So I did:

nmap <F8> o<Esc>
nmap <F9> O<Esc>

Which works fine for me.


<S-Enter> and <CR> will work separately in gvim but not in urxvt. See http://stackoverflow.com/questions/598113/can-terminals-detect-shift-enter-or-control-enter


Since I have inoremap jj <Esc> in my .vimrc, it take not too much to type ojj or Ojj.


To add a blank line below or above and keep the cursor in place, I think this is easiest:

nnoremap <C-J> m`o<Esc>``
nnoremap <C-K> m`O<Esc>``

It uses the jump list to remember the cursor position, so it does clutter up that list. But I don't mind. You could use any other mark, like so (uses mark a):

nnoremap <C-J> mao<Esc>`a
nnoremap <C-K> maO<Esc>`a

This mapping interferes with command execution in the command-line window. The command-line window can operate in normal or insert mode and in both <CR> executes the command from current line. Using nmap instead of map in the mapping declaration partially fixes the problem. Then, to execute the command, you must enter the insert mode and press <CR>. While this is a feasible workaround, I prefer to dispense with this mapping and type oii to insert a new line (ii being my map for <Esc>).

Excellent point! :map applies to too many modes, I went ahead and made it :nmap. For the other problem, we should edit the mapping to detect the command-line window, like in Syntax folding of Vim scripts. Probably this will need an <expr> form of the mapping to do easily. --Fritzophrenic (talk) 15:01, June 27, 2013 (UTC)
