Playback
Editing
The selected area decides what a shared shortcut does. For example, arrow keys nudge a selected canvas element; without a nudgeable selection they step through frames.
Keyframes and recording
During gesture recording, drag records position, scroll records depth,
Shift-drag records 3D rotation, Option/Alt-drag records rotation, and
Command/Ctrl-drag or scroll records opacity or scale.
Canvas and panels
Use the Shortcuts and tools button beside the playback controls for the
built-in shortcut list, work-area controls, and jump-to-frame field.
