Neovim: Select an autocomplete option with <tab> instead of <return>

Question

In the example below, how do I use <tab> to select HttpResponse the item instead of <enter>? I'd like to make this change permanent.

This is using Kite within vim in case it matters.

Answer 1

You need this map:

inoremap <expr> <TAB> pumvisible() ? "<C-y>" : "<TAB>"

If PUM (complete menu) is visible, then execute <C-y> (which selects an item), otherwise, do a normal tab.
