Hello,

I tried to map the function er/expand-region onto C-@ with:

    (global-set-key (kbd "C-@") 'er/expand-region)

but, in Windows Emacs (tested as well with a minimal configuration
file), C-h k C-@ returns @...

In the same order, C-k C-M-@ return M-@...

That problems seems to be limited to some versions or platforms, as that
key binding appears on the author's page
(http://emacsrocks.com/e09.html).

Best regards,
Seb

I don't see this particular problem, although up to version 24.5, Emacs
doesn't receive C-M-) events, there's no response at all.  It works in
25.1 though, I think there were some changes to keyboard handling, which
maybe have fixed OP's problem as well?

I was going to wait if the OP might respond, but the mail bounced, so
I'll just close.
