I'd like to switch the behaviour of the <Down>
and <C-n>
keys when the popup menu (like from omnicompletion) is visible (and <Up>
/<C-p>
respectively).
The following two mappings work (actually only in neovim; in vim they insert arbitrary lines with single letters on each keystroke):
inoremap <expr> <Down> pumvisible() ? "\<C-n>" : "\<Down>"
inoremap <expr> <Up> pumvisible() ? "\<C-p>" : "\<Up>"
The following don't
inoremap <expr> <C-n> pumvisible() ? "\<Down>" : "\<C-n>"
inoremap <expr> <C-p> pumvisible() ? "\<Up>" : "\<C-p>"
What am I doing wrong? I tried it with --no-plugin -u NONE
to assure that they don't conflict with some other setting or plugin, but that is not the case.
