Global pitch-step-sequencer in Rapture?

I'm learning Rapture and would like to know if there is a fast way of using the step-sequencer globally for PITCH?

Or do I have to copy and paste the steps from each layer?

I'm also wondering how to undo actions, are there any key-commands I can use (I'd really like to see a list of these for mac - if they exist!)

Thanks!
