Tabbing in Deoplete is Backward

Question

When I trigger the autocomplete menu in Deoplete, the tab key's behavior is backward. For example, let's say I pop up an autocompletion drop down.\

When I hit the tab key, I would expect Neovim to select the first item in the list. Instead, it selects the last.

I'm not sure if this behavior is specific to Deoplete or is a generic issue with Neovim.

Answer 1

The trick to this one was to remap tab and shift-tab.

inoremap <silent><expr><tab> pumvisible() ? "\<c-n>" : "\<tab>"
inoremap <silent><expr><s-tab> pumvisible() ? "\<c-p>" : "\<s-tab>"

There are more instructions on how to improve the popup menu in the Vim wiki.
