Emacs on Windows ignoring "\C-)"

Emacs on Windows ignoring "\C-)"

[Joe]

Hey all,

Emacs doesn't seem to capture the key sequence "\C-)" (ctrl-shift-0).
This input doesn't appear in (view-lossage).  I've tried loading emacs
without an init and site file and the behavior is the same.

Does anyone else have this problem, or have a solution?

I'm using Windows 7 with:
"GNU Emacs 23.1.1 (i386-mingw-nt6.1.7600)
 of 2009-07-29 on SOFT-MJASON"

Thanks,
Joe

what happens when you type
C-h k C-)

are there any messages in the echo area or *Messages* buffer?

When I press C-h k C-), emacs (actually `describe-key') continues to
wait for a keypress.  It doesn't do anything in response to C-).

There are no messages in the echo area or in the *Messages* buffer.

Interestingly, if I force the issue by evaluating (describe-key (kbd
"C-)")), emacs reacts correctly and brings up the help for function
associated with the key.

I thought maybe I screwed up something on Windows, but logging in as a
different user results in the same behavior.

Any more ideas?

I don't see this problem on Windows XP SP2.

I do not see this problem either on Windows XP, but I wonder if you
have sticky keys turned on, Joe?

Does it look like this in the minibuffer?
 Describe key (or click or menu item):  C-)-
IOW, ending with a with a dash, with the cursor after the dash?

If it does, that's a sign that `C-)' is defined as a prefix key, for some
reason. `C-h k' waits for the rest of the key sequence following the prefix.

You can try this, to try to get some more info: `C-) C-h'. With a little luck,
if `C-)' is in fact a prefix key this will show you help about `C-)' and its
possible completions. The command names bound to the keys might give you a clue
about what library is binding `C-)'.

You say that this also happens to you if you start Emacs using `emacs -Q'? If
so, then consider filing a bug: `M-x report-emacs-bug'. AFAIK, `C-)' should not
be bound to anything by default in virgin, vanilla Emacs. (describe-key (kbd
"C-)") should say simply `C-) is undefined'.

If this same behavior does not occur with `emacs -Q', however, then look in your
init file for something that is defining `C-)' (as a prefix key). To find it,
use binary search: comment out half your init file, then half of that, and so
on, until you narrow down the guilty part. Sounds long, but it's actually very
quick to do.

What does that help say? If it says `C-) is undefined', then there is likely a
problem with `describe-key'. If it gives some command name, then take a look at
the library that defines that command.

First off, thanks for the replies.  Now to address those replies:

> I don't see this problem on Windows XP SP2.

I'm beginning to suspect the problem is related to Windows 7.  Does
any one
running Vista or Windows 7 have this problem?

Sticky keys are off.

No, it completely ignores "C-)".  For example the key sequence:

"C-h k C-) g" results in "C-h k g".  Emacs describes the `self-insert-
command'
because that's what 'g' does.

Yes, "emacs -Q" also ignores "C-)".  I'm hesitant to file a bug report
because I
think I might have done something silly on my system.  I'd like to
first see if
"C-)" is recognized in another application.  Are there any Windows
applications
to show keypresses?

> What does that help say?

It shows the help for `paredit-forward-slurp-sexp', which is what I
expect.

a quick google search indicates that C-) (or Ctrl-Shift-0 in Windows 
parlance) may be a shortcut for switching input language

Thanks, changing the key setting solves my problem.  Didn't think to
search for ctrl-shift-0.
