I forgot to add a vital piece of info. I also have vim-tmux-navigator. Not the Vim plugin, but the minimal necessary code stolen from it.
function! TmuxOrSplitSwitch(wincmd, tmuxdir) abort let previous_winnr = winnr() silent! execute "wincmd " . a:wincmd if previous_winnr == winnr() call system("tmux list-panes -F '#F' | grep -q Z \|| tmux select-pane -" . a:tmuxdir) endif endfunction let previous_title = substitute(system("tmux display-message -p \ '#{pane_title}'"), '\n', '', '') let &t_ti = "\<Esc>]2;vim\<Esc>\\" . &t_ti let &t_te = "\<Esc>]2;". previous_title . "\<Esc>\\" . &t_te nnoremap <silent> <C-h> :call TmuxOrSplitSwitch('h', 'L')<CR> nnoremap <silent> <C-j> :call TmuxOrSplitSwitch('j', 'D')<CR> nnoremap <silent> <C-k> :call TmuxOrSplitSwitch('k', 'U')<CR> nnoremap <silent> <C-l> :call TmuxOrSplitSwitch('l', 'R')<CR> Turns out, the control code "^[[O" was emitted from TmuxOrSplitSwitch(). All I had to do was prepend a ":h :silent" (not ":h map-<silent>; that was already there) to the keymap. Now Vim corrupt the window with that control code. -- Enan -- -- You received this message from the "vim_use" maillist. Do not top-post! Type your reply below the text you are replying to.
