Those devices have some additional buttons:
- A 'Windows Mobility Center' button that sends Windows+X
- A 'Dell audio preset switch' button that sends key code 0xe02a on
press (with auto-repeat) and 0xe02c on release
- An 'instant launch' button that sends key code 0xe024
The first one doesn't require handling; the two latter ones do not have
a real meaning in Linux, so bind them to launcher keycodes.
