Anywhere in the app, press and hold the Command (⌘) key on your connected keyboard to view a list of available shortcuts. There are some shortcuts that work no matter where you are, while others are specific to your current view. Some locations may have more than one overlay screen's-worth of shortcuts available; in that case, browse between pages by swiping left or right with the Command key held down.

Redo (Shift-Command-Z)
