"C-h k" reports "<keybinding> is undefined"

"C-h k" reports "<keybinding> is undefined"

[York Zhao]

Hi there,

I have noticed this problem for awhile that for some of the key bindings "C-h k"
shows "<key binding> is undefined". For example, when I type "C-h k M-q", it
says "M-q is undefined", but I really did bind it to my own function and my
function was working because If I set breakpoint in the function where "M-q" was
being bound to and press "M-q" I was able to get into the function. The key
bindings not being shown by "C-h k" is not limited to "M-q" but a bunch of
others as well. However, there are also a number of other key bindings that can
be reported by "C-h k". I have no idea why this is happening. Can somebody tell
me with this?


Thanks,

York

Forgot to mention that I'm using the latest emacs from git:

commit 0ade109630e14430d3eb48c29417804130a0cbff

    Fix trailing whitespaces in Org files.

I built it under windows using mingw.

1. This can happen because `M-q' is not in fact bound in the current context
(e.g. current buffer).  Are you sure that you are using `C-h k M-q' in the same
buffer where the command is effectively invoked whenever you hit `M-q'?

2. There could be an Emacs bug.  You are apparently using a development version,
not a released version of Emacs.  If #1 above shows that `C-h k M-q' really
should be showing a binding for your command, then consider reporting an Emacs
bug, using `M-x report-emacs-bug'.  The Emacs developers will determine whether
there really is a problem.

My "M-q" is a global binding, and most importantly, while "C-h k M-q" reports
undefined binding, typing "M-q" invoked my function. After all, it's not just
"M-q" that was reported undefined binding, a number of other bindings are not
being to be reported by "C-h k".

Since I have never been able to get email work in Emacs, I'm afraid I'll not be
able to report bugs inside Emacs using "M-x report-emacs-bug", is there any
other way of reporting Emacs bugs?

Thanks a lot,

York

AFAIK if you have mail already configured in general (not for Emacs), then `M-x
report-emacs-bug' will prepare the mail content, subject, and destination, and
then call up your mail client.

E.g., on Windows, I use Outlook as my mail client, and `M-x report-emacs-bug'
causes Outlook to open a new message. I then hit `C-v' to paste the bug-report
content (automatically saved to the clipboard) into the message body.

Even if you do not use Emacs for mail, `M-x report-emacs-bug' can help, because
it puts you in an editing buffer where you type your bug report, and that buffer
already has a bunch of important info that can help the Emacs developers.

E.g., it shows exactly what your Emacs build is (hence which Emacs version and
which platform), and it lists a bunch of variable values that might be
pertinent.

So you can just use `M-x report-emacs-bug' to get that data, and then paste it
into an email message, if you like.  You definitely need not configure or use
Emacs for email.

Thank you very much for the help, I have already sent the bug report by copy and
paste, exactly as what you suggested. And I have received an acknowledge from
the list. Hopefully somebody will take care of this soon.

Could you please show the code that establishes the binding?

Hi Tassilo,

Thank you for the response and as Mike just pointed out this seems to be a
problem with Evil package. But anyways here's my code that binds the key.

(global-set-key (kbd "M-q") 'fill-paragraph-or-region)


Thanks,

Ah, ok.

Well, that's clearly correct.

Hi York,

I assume you're still using Evil.

It's (unfortunately) a long standing bug[1] that affects mostly
(exclusively?) the M-* bindings in non-emacs states and that has
probably been forgotten because it never went to the issue tracker.

Please be so kind and file it if you have time.

Michael

Hi Mike,

Haven't seen you for a long time, how's everything? I'm still using Evil and
loving it, what about you?

Thank you very much for pointed out this to be an issue in Evil and I have
posted to the Evil issue tracker just now.

https://bitbucket.org/lyro/evil/issue/63/c-h-k-reports-is-undefined

To the list:

I apologize for having reported a bug which may have nothing to do with Emacs.


Thanks,

York
