* Option-F11 (PC: F11 alone): Full screen mode
* Option-Cmd-B (PC: Ctrl-Alt-B): Open/close browser (and arrow keys scroll).
* Shift-TAB (PC: TAB alone): Switches between Arrange View and Session View (the linear track view and live performance-oriented clip view, respectively).
* Shift-SPACE: Starts/stops playback at the current playhead position; i.e., it’s a pause function. (SPACE alone starts at the beginning of the song.)
* Cmd-1,2,3,4 (PC: Ctrl-1,2,3,4): Adjusts the active quantization grid in current clips while editing. This one is really essential, of course.
* Cmd-arrow keys (PC: Ctrl-1,2,3,4): Controls Loop Region length. This really speeds up editing in a big way. Up/down uses a large increment (doubling/halving), whereas the right and left arrow keys use a small increment.
* Cmd-D (PC: Ctrl-D): Duplicate (and it duplicates everything, so it’s handy in Session View)
* Cmd-I (PC: Ctrl-I): Insert silence
* Cmd-B (PC: Ctrl-B): Draw Mode – essential for being able to switch between drawing and selection in clip piano roll, envelopes, etc.
* Shift-Cmd-I (PC: Ctrl-Cmd-I): Capture and Insert Scene. This cleans up your set by taking combinations and automatically inserting them in scenes.
