Media Keys
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.
