Subject: C-M-SPC is not working

[Message part 1 (text/plain, inline)]

Hi,

I have been using mark-sexp often because I am working with Common Lisp.
Until now, the binding C-M-SPC has worked out pretty well.

For some reason that I do not understand, the binding has changed. Now,
emacs says mark-sexp is bounded to C-M-@ (which does not really work using
the keyboard, by the way).

This is my humble config file
<https://github.com/pdelfino/my-emacs-config/blob/main/.emacs>. I am not
sure why this has happened. As you see, I have not touched on this specific
point.

I can only use mark-sexp with the `M-x mark-sexp` which is not very handy.
I wish the keybinding worked out.

Is this some side-effect from another modification? Why did this happen?
And how can I fix it?

;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;

Recipe using "emacs -Q"

1 - Create an emacs lisp file, could be .emacs;

2 - Insert any valid s-expression, could be
(load (expand-file-name "~/.quicklisp/slime-helper.el"))

3 - Put the cursor -!- in the beginning of the s-expression
-!-(load (expand-file-name "~/.quicklisp/slime-helper.el"))

4 - Try using `C-M-SPC` or `C-M-@` to achieve mark-sexp. It does NOT work
(and it should work).

5 - Press M-x and execute `mark-sexp` it DOES work. Thus, all the
s-expression is selected.

I cannot reproduce this in Emacs 26.3.  If, after step 4, you type
"C-h l" (that's the letter ell, not the digit one), what do you see?

Please, see the screenshot attached.

Not sure if this is related, but I switched the control key with the
caps lock key in my Ubuntu. You can how I did it here:

I see no C-M-SPC or C-M-@ anywhere in sight (assuming you show all of
the relevant parts of the *Help* buffer).  Which probably means Emacs
didn't receive those keys, and that explains why it doesn't work for
you.

So I think this is indeed something with your keyboard configuration.

If you undo that swapping, does the problem go away?

More information was requested, but no response was given within a
month, so I'm closing this bug report.  If the problem still exists,
please respond to this email and we'll reopen the bug report.

(Oops; that was premature -- it's actually only been two weeks.  Had
sorted the debbugs in the wrong order.)

Hi guys,

Sorry for taking so long to answer.  Thanks for the help!

You guys asked:

If you undo that swapping, does the problem go away?


Yes, it does. The problem is the swapping.

But I need it more than C-M-SPC working. So, I am improvising C-M-m
until I manage to swap the keys in a better way.

Best,
Pedro
