That may have been me.  Used TAB tho, rather than M-TAB.

Keymap in message mode?

[Jens Lautenbacher]

Sometime ago, if I remember correctly, someone posted a piece of code
which changed the behaviour of the M-Tab in the header of a message
according to the current headerline(so one could bind it in the to
line to bbdb-complete-foo-bar and in the newsgroup line it would do a
complete over the newsgroups.)

Does anybody know who wrote this piece of code and/or where I can get
it?

Thanks,

Why is this not part of gnus? I think this is a *very* nice
feature. Maybe you could add customization support to it?  Then Lars
could use a default value which mimics the current default value and
it would still be very easy to change it if one uses bbdb.

I agree. I think it should be part of message.el as well. I use this package
constantly and can't imagine using message-mode without it! Thanks, Kai!
