it will complete "boingboing" without any further effort from me

Nope, you have to explicitly trigger completion with a hotkey.

I'm with Cory, completion is cool. It's one of the reasons I like tcsh so much.

OK, now somebody has to post about how deluded I am and how much better completion is in bash/zsh/abcdefgsh. Perhaps we could combine that with an emacs/BBEdit thrash. (Me, I use both.)
