vim: Use insert-mode-like completion for command completion

Question

Is it possible to use a vertical command line completion just the way it appears when using CTRL-N in insert mode?

Answer 1

I personally like

set wildmode=longest,list

It behaves sort of like bash completion. (It also shows the same information as <c-d> when you hit <tab>).

Answer 2

You can have such a menu when doing completion in the command-line window (q:) but you can't have it in the command-line itself.

But set wildmenu (see also :help wildmode) is good enough in my opinion.
