No, it's M-D.  You can usually simulate it with ESC-D, but it's not
the same thing.  Emacs on serial terminals used to accept a character
with bit 7 set as M-<character>, and that's what it did (I think, I'm
on thin ice here) with the ESC prefix.  Nowadays, with an X interface,
it handles things differently.

Yes, I acknowledged this elsewhere.  I still think that this would be
the exception, though.
