1.7 for Mac is out/Anyway to make new shortcut for Simulator?

So I downloaded v 1.7 yesterday and I like the new train options. However, what I don't like is that Command-U--which was a shortcut to the Simulator--now brings up the new Support Panel instead.

So you either have to use the Coaster drop-down menu to start the Simulator, or add the icon to your toolbar. Does anyone know of any ways to make a Simulator keyboard shortcut?

I also didn't like the change from Command-Y to Command-Option-Y to split-up track segments in v 1.6. It may seem really trivial (and especially for such an inexpensive program) but once you make a keyboard shortcut, you should leave it alone!
