Click a field and press the key combination you want — it takes effect immediately. Recording a new key replaces that action’s default; Reset puts it back (Save’s export alias returns on Reset too). A key that’s already used by another shortcut — including app keys like L / E / S — is refused with a note.
- Hover any button to see its tooltip — most include the shortcut in brackets like
[S] or [C].
- Buttons disable themselves when their shortcut wouldn’t do anything (e.g. the Stack button needs ≥2 frames selected; before that,
S is a no-op).
- macOS users: the symbols ⌘ = Command, ⌥ = Option, ⇧ = Shift.
