Are you perhaps talking about limiting the candidates for completion?

If the only difference between these commands is completion of the
argument, here's an idea.

* Make TAB and ?, when a completion list is displayed, toggle the
completion mode between commands-only and all-functions.

* Arrange a way to show on the screen which completion mode is in use.
Perhaps in the completions list buffer.

* Make C-h f start out with completion in commands-only mode.  That
will be good for beginners.  If you want to complete a noninteractive
function name, toggle the completion mode.

This interface involves no new commands, and no new bindings, and it
is easy to discover.
