These keycodes are not part of the Keyboard/Keypad usage page. The SYSTEM_
keycodes are found in the Generic Desktop page, and the rest are located in the Consumer page.
?> Some of these keycodes may behave differently depending on the OS. For example, on macOS, the keycodes KC_MEDIA_FAST_FORWARD
, KC_MEDIA_REWIND
, KC_MEDIA_NEXT_TRACK
and KC_MEDIA_PREV_TRACK
skip within the current track when held, but skip the entire track when tapped.
