So, with the iPhone simulator running on your Mac, you can click with your mouse to simulate a touch. I'm wondering, how do you simulate multi-touch? Like, how would you simulate a pinch/zoom, or a rotate?

Hold down the Option key and click/drag. Option+Shift also simulates a two finger scroll.

I wonder if the new macbookpros with the multi touch trackpads could be made to use with this. It is sort of coincidental timing to release it.
