Yes, I know about the Tab-Triggered commands that come with TM (should
have been more explicit about that in the message, I guess). But when
I change the headings--which I often do--I like to readjust the
lengths of the underlines with a single keystroke, not an
erase-equal-tab sequence.

Now that I think of it, a snippet that automatically types the
underline as you're typing the heading text would be really cool. Not
productive, maybe, but cool.
