Type C-h c (`describe-key-briefly'), followed by C-M-..  (That's C-M-.
followed by a full stop.  You don't type the full stop; I typed it to
indicate the end of my sentence.  Yikes! :-)  This will show you what
key sequence Emacs saw.

Maybe your keyboard hasn't been set up to generate proper key codes
for C-M-.  Try C-h l `view-lossage' after typing M-. and C-M-..  This
will show you what raw key codes Emacs actually received.

Also, please tell us your operating system and environment.
