"Lock Actor" on the upper jaw is a great idea. It's not really meant to be moved around much.

I didn't give the lower jaw a fancy name yet because I was planning to slave it to face morphs, anyway. I could do it the other way around, but I suspect people are used to finding things like "Mouth Open" on the face, so I should probably leave it that way.
