One of the things I use it for is "unseeing" a message. Let's say I see someone has emailed me, I'm about to go out, want to take a peek at the message but don't want to mark it as seen — or alternatively I look at a message, think "gosh that's gonna take a lot of work to deal with" so want to mark it as unseen again, so I come back to it. My unseen-sequence is "un", and my previous-sequence is "ditto", so I have this alias to "unsee" whatever I just looked at:
mark -sequence un -add ditto .. then I have another alias to do the first job — looking at something without "seeing" it: show !*; mark -sequence un -add ditto I bet there are magic command line switches to do this now (seems to happen half the time I post these days!), but I've had these for a long time and use them regularly.
