overriding/disabling conflicting keybindings

[towc]

I use vim inside of tmux, and I set vim up so that when I press c-j/c-k, I go to whatever is below/above, either a vim window, or a tmux pane.

Vmail is overriding this by opening the previous/next email. I tried to put a bunch of stuff in vim_opts in the .vmailrc, but I can't seem to disable/re-override (ideally elegantly) these mappings. Any suggestions? What can I do?

Also, running :nunmap <buffer> <c-j> after opening vmail correctly restores the behaviour in that particular buffer, but I don't want to manually do that every time

The mapping is defined here:

vmail/lib/vmail.vim

Lines 864 to 874 in 9ccbb59

	if !hasmapto('<Plug>VmailMessageWindow_ShowNext')
	nmap <buffer> <C-j> <Plug>VmailMessageWindow_ShowNext
	nmap <buffer> <leader>j <Plug>VmailMessageWindow_ShowNext
	endif
	nnoremap <buffer> <unique> <script> <Plug>VmailMessageWindow_ShowNext :call <SID>show_next_message()<CR>
	if !hasmapto('<Plug>VmailMessageWindow_ShowPrev')
	nmap <buffer> <C-k> <Plug>VmailMessageWindow_ShowPrev
	nmap <buffer> <leader>k <Plug>VmailMessageWindow_ShowPrev
	endif
	nnoremap <buffer> <unique> <script> <Plug>VmailMessageWindow_ShowPrev :call <SID>show_previous_message()<CR>

So if one wants vmail to not map c-j and c-k, they would need to add mappings for these <Plug>... functions in their .vimrc. For e.g. if you want only the <leader>j/<leader>k mappings to go to the next/previous message, define the following in your .vimrc:

  nmap <buffer> <leader>j <Plug>VmailMessageWindow_ShowNext
  nmap <buffer> <leader>k <Plug>VmailMessageWindow_ShowPrev

Let me know if this works for you.
