A key by its KeyboardEvent.code, such as "KeyF", "Digit1", "ShiftLeft" or "Space": the key’s place on the keyboard, whatever letter the player’s layout prints on it. Every code of the standard keyboard but ⌘ and the Windows key, MetaLeft and MetaRight, which let go of every held key, since macOS sends no release under them.
