Is it possible to make <C-W><C-L> command to make split on the right, if it's the rightmost pane opened? Otherwise, it would behave like regular move. It's something like "conditional splitting" I would say.

Example: I've got two panes opened, split vertically. Cursor is currently on the right pane. I press <C-W><C-L> and I create third pane and my cursor is moved there.

If I press <C-W><C-L> from the leftmost pane, nothing unusual happens, I just move to the already existing pane to the right.

P.S.: which are common bindings for splitting panes among Vim users?

  • As Dedowsdi mentions, Im fine with usual commands. I use either <C-w><C-v/s> if i want to split the same file (not often the case, but useful to work on two parts of the same file), or :[v]split to split to other files files.

  • D. Ben Knoble, thank you for sharing your experience. Maybe I'll discover the same for myself when I become experienced enough with Vim. But :[v]split will be handy for sure, thanks! May 29, 2019 at 13:27

Split and move if window doesn't change after <c-w><c-*>:

nnoremap <c-w><c-j> :call <sid>smart_split('j')<cr>
nnoremap <c-w><c-k> :call <sid>smart_split('k')<cr>
nnoremap <c-w><c-h> :call <sid>smart_split('h')<cr>
nnoremap <c-w><c-l> :call <sid>smart_split('l')<cr>

function! s:smart_split(cmd)
  " original window number
  let wn = winnr()

  " try to move to other window
  exec 'wincmd ' . a:cmd

  " do nothing if window changed
  if wn != winnr() | return | endif

  " otherwise split vertical or horizontal based on a:cmd
  exec 'wincmd ' . (a:cmd =~# '[lh]' ? 'v' : 's')

  " move to new window. You only need this 50% of time.
  exec 'wincmd ' . a:cmd

I don't used this, i'm fine with default window splitting command binding.
