Recipe from emacs -q:
1. M-x gnus
2. Select any group
3. Select a random article
4. do `W C-h' or C-h m

W C-h simply does not work while C-h m works, but does not show the
bound keys.

FWIW I'm unable to reproduce this, using Emacs master. I'd be pretty
surprised if Gnus were able to break such low-level functionality, too.
Can you give us any more clues? Is this something that only started
happening recently?

In gnus-article-mode, all self-inserting keys are bound to
gnus-article-read-summary-keys, which does special things.  They are
_not_ prefix keys.

(I didn't realize you meant with point in the article, sorry)

(Sending this back to the bug report...)

Yes, I'm able to reproduce it, and it sent me down a really awful rabbit
hole -- gnus-art.el goes to huge lengths to make summary-mode
keybindings available in article mode. It uses this:

(substitute-key-definition
 #'undefined #'gnus-article-read-summary-keys gnus-article-mode-map)

to redirect all unbound keys to the `gnus-article-read-summary-keys'
function, which manually reads keys and dispatches to tweaked versions
of summary-mode commands.

Your immediate issue is caused by the fact that
`gnus-article-describe-bindings', which theoretically should be
responsible for telling the user about all the redirections, is only
aware of the "S" keymap prefix. It doesn't know all the ways in which an
'undefined binding might get translated into a valid summary-mode
command, and can't show you those.

To be honest, I don't think I'm going to be able to fix this. If we keep
the current implementation, `gnus-article-describe-bindings' would have
to be made aware of the additional redirections, and I wouldn't even
know where to start.

It could be that Elisp has better tools for this situation by now (the
original architecture was in place before 1997), but I'm not sure what
those tools are. Perhaps someone will chime in with a helpful
suggestion...

Eric

Strange as it may sound, I see no grave problem here: C-h is not
guaranteed to work after any arbitrary prefix, anyway.  So if that is
too hard to fix, we could just punt and leave it unsolved.

What about "C-h b" -- does that work in the situation described by the
recipe?

I'm inclined to say it's too hard to fix! The only cleaner solution I
can think of is to actually define article-mode versions of all the
summary-mode commands we'd want to call, which would also provide a
place to do the necessary article-specific adjustments. That's a lot of
very tightly-coupled code, though.

No, that doesn't really work. The gnus-article-mode bindings are listed
under a "fundamental-mode Major Mode Bindings:" heading (??). That
includes gnus-article-mode's own keybindings, and the summary-mode
bindings that have been explicitly attached at the "S" prefix, but
nothing else.

I don't know, I don't see a good solution to this without a massive
rewrite, which I don't have the stomach for right now. Should we leave
the bug open, since it's a real problem?
