I'd like to map Leader+e in normal mode to showing the auto completions of files to edit.
nnoremap <leader>e :e<space><tab>, but it shows
:e ^I, where the tab gets rendered as
^I rather than triggering the auto completions.
nnoremap <leader>e :e<space> correctly prints
:e but I obviously have to hit Tab manually in this case.
How can trigger the auto completions to show up in a key binding?
