Oh god, BBEdit. I brought my own iBook to work for the duration of the last job because I couldn't stand the editors offered on Windows. That wasn't OS bigotry, it was editor bigotry. I've been using BBEdit for, what, ten years? - from when it still had a DRieUxCaPS plugin. At least eight of those years has been for salary, wage, and valuable consulting fees. These days, being able to type "bbedit filename" from shell makes me giggle.

You should do with BBEdit what you should do with any app you intend to use for more than half an hour: Open the preferences dialog and tweak. I spend an hour on any new installation of BBEdit to configure it MY way and give it MY key chords. If your muscle memory favors Brief keystrokes, use those. It's already got a built-in emacs mode, so it's not like you should feel shame.

BBEdit's cvs widget saved me hours of work at my last job since I can key-chord a checkin or update without breaking stride on whatever I'm writing. There are some fine scripts circulating, many free (I can't recommend any but the Daring Fireball weblog occasionally flags the goodies, and I'm looking for a reason to try out bbautocomplete).

The message board kills HTML, so some URLs:
