Nothing means that if I type 'M M e', emacs immediately responds that this is undefined, without waiting for any further keystrokes.

It's not defined anywhere in my .emacs or .gnus.el file. In fact, the sequence originally came from an example Peter Münster posted
to this list, so it evidently worked for him.

Yes, I'd have to figure out how to do the rest of the behavior (moving to and showing the next message in the group). As I
mentioned, I'm not lisp-savvy, but I could figure this out in time.

I'm still puzzled about why it suddenly stopped working, after being in use for months.
