This bug report will be sent to the Bug-GNU-Emacs mailing list
and the GNU bug tracker at debbugs.gnu.org. Please check that
the From: line contains a valid email address. After a delay of up
to one day, you should receive an acknowledgment at that address.
Please write in English if possible, as the Emacs maintainers
usually do not have translators for other languages.
Please describe exactly what actions triggered the bug, and
the precise symptoms of the bug. If you can, give a recipe
starting from `emacs -Q':
Dear Wmacs Hackers,
I often find myself in a position where I still know some prefix key, but not the second key. For example I hit `C-c /` in mailcrypt-mode, but I'm not sure whether I fetch the key with `k` or with `f` (the latter actually calls forget passphrase). In that case, I am forced to either consult C-h m or use the menu - both of which does not feel very elegant.
Instead of that, it would be nice if emacs could show a completion-list similar to the function completion with M-x. This would allow discovering options while using emacs instead of browsing menus or tutorials, hunting for new ways of working more efficiently.
Best wishes,
Arne
If Emacs crashed, and you have the Emacs process in the gdb debugger,
please include the output from the following gdb commands:
`bt full' and `xbacktrace'.
For information about debugging Emacs, please read the file
/usr/share/emacs/24.3/etc/DEBUG.

1. You can hit `C-h' to see the list of keys that start with that
prefix key. E.g., `C-c / C-h' shows you all of the keys that start
with prefix key `C-c /'.
2. If you use Icicles then you can hit `S-TAB' to complete the
prefix key. Buffer *Completions* shows the possible completions.
Type text matching the rest of the key name to finish the key.

#1 is available in vanilla Emacs. It might well be all you need.
#2 requires Icicles. It corresponds more exactly to what you
requested, IIUC.

You can easily type C-h to get a list of keys available on any prefix.
If Prefix + C-h is shadowed, use Prefix + ?. In your case C-c / ? or C-c
/ C-h. C-c / ? only works in trunk i.e. 24.4
HTH,
Leo

Wow, I did not know that... thanks a lot!
That does what I need. Sorry for the disturbance...
Best wishes,
Arne
PS: Ongoing saga: Emacs can already do it.

FWIW, `C-h' has worked this way forever.
