Remapping Keys in Insert Mode Completion ( Autocomplete / ^X )

Question

Using: NeoVim

I would like to remap j/k in Insert completion mode:

• tab starts autocompletion (done, used :help ins-complete example)
• j/k navigate results like <C-n>/<C-p>

If I understand correctly the Insert completion mode simply shares rebinds with the normal Insert mode, so there's no inoremap equivalent (i.e. pnoremap for comPlete). So is there some way of doing this?

I would prefer not to use a plugin. A best case solution would not break my existing inoremap jk <esc> binding, but I would also be interested in solutions that break that.

Answer 1

Something like the following should work and still allow your jk to function:

imap <expr> j pumvisible() ? "\<C-n>" : 'j'
imap <expr> k pumvisible() ? "\<C-p>" : 'k'
