<sup>1. The Linux kernel HID driver recognizes nearly all keycodes, but the default bindings depend on the DE/WM.
2. Treated as F13-F15.
3. Must be held for about three seconds, and will display a prompt instead.
4. Holding Shift+Option allows for finer control of volume level.
5. Skips the entire track in iTunes when tapped, seeks within the current track when held.
6. WMP does not recognize the Rewind key, but both alter playback speed in VLC.</sup>
