Keyboard shortcuts
On macOS, Command stands in for Ctrl in every shortcut, and Control+click is a right click.
The Computer MIDI keyboard is on by default (Ctrl+T switches it). While it’s on, plain letter and number keys play notes, so keys marked * below only work with it off. Most tool letters also work with Shift held, which it leaves alone.
