No, there is no shortcut for this function. You can access to some properties using shortcuts (P for Position, R for Rotation, E for Effects, M for Masks, and some other) or you can use the quick searh over your timeline to access for a specific parameter if you know its name.
Yeah, those are part of my current workflow. I was hoping for something to step through shape layer properties. Oh well, After Effects already does such an amazing amount of stuff...can't expect it to do everything. Thanks for the reply.
