I'm on a MacBook Pro, too, Kahlua. If you click and hold on the trackpad you can use another finger to turn the camera. Yeah, I know, not much of an improvement over the keystrokes. :/ When I tried it yesterday, I was pretty much doing everything by trackpad--movement, skill selection, stims...but it's a pretty steep learning curve going to that from touchscreen and I've got a long ways to go.
