That doesn't work for all (even most) prefixes. It doesn't work for C-s, for
instance (isearch-mode-map).

If you use Icicles, then just use the prefix, followed by S-TAB. In this case,
C-x S-TAB. 

All possible key-sequence completions of prefix C-x are then completion
candidates - they are shown in *Completions* along with their bindings
(commands). 

You can see the complete command definitions of selected candidates during
completion using C-M-RET or C-M-mouse-2, or you can see the definitions of
several or all candidates, in order, by repeating C-next.
