 <sup>1. The Linux kernel HID driver recognizes [nearly all keycodes](https://github.com/torvalds/linux/blob/master/drivers/hid/hid-input.c), but the default bindings depend on the DE/WM.</sup><br/>
 <sup>2. Treated as F13-F15.</sup><br/>
 <sup>3. Must be held for about three seconds, and will display a prompt instead.</sup><br/>
 <sup>4. Holding Shift+Option allows for finer control of volume level.</sup><br/>
 <sup>5. Skips the entire track in iTunes when tapped, seeks within the current track when held.</sup><br/>
 <sup>6. WMP does not recognize the Rewind key, but both alter playback speed in VLC.</sup>
+<sup>7. The Globe key requires `GLOBE_KEY_ENABLE = yes` to be set in `rules.mk`. When pressed it will reveal the emoji picker, and it can be combined with other keys. Note however that Globe+F-keys or Globe+arrow do not work.</sup>
