Wow, never knew that, Dana. I've always been turning Control Strip off, trashing Control Strip Preferences, then rebooting. Nice to know there's an easier way!

I had only known about non-option dragging to just change its left/right size.

Just to clarify, I just tried it, and it is Option, not Command. But it's very nice, you can even make it 'dock' to the right side of the screen instead of the left.
