In the distributed 4.1bsd Mail (ucbmail) there are several extremely
useful commands which I haven't seen  documented anywhere.  Should be added
to man/tutorial entries somewhere.

1. ~:   For example, here's the way to re-read
	the message you're replying to after you've started replying:

	~: t	(type current msg)

2. ~f [n]	Just like ~m (interpolate/forward message), but without
		shifting it.

3. Capital 'R' command to Mail replys only to the sender.
   I've heard rumors that it's been known to ignore the reply-to field in 
   this case, but I can't duplicate it.
