How to operate on selection in mutt?

This is a very simple thing, but I just can't make myself remember it. So here is how it's done:

1. Tag some of messages (e.g. by using t, T, Alt-T and Ctrl-T shortcuts)
2. Press ; (which is bound to the tag-prefix function by default) followed by any other command you want to apply to the selected items.

Basically, that's all I wanted to write.
