Add keycodes for multi-functional devices, e. g.:
KEY_SCAN
KEY_1_1

Add keys for mobile phones:
KEY_CALL (KEY_PHONE?)
KEY_HANGUP


PIM:
PIM: KEY_CALENDAR, addressbook is probably missing (let's look to spitzkbd.c), KEY_MAIL (and obsolete KEY_EMAIL)

Craddle key:
KEY_SYNC

OSD control keys.

Verify that all keys are present for:
- standard directories
- standard PIM apps
- OK in the middle of arrows
- separate controls for AV - bass, middle, treble, saturation, brightness,...


Maybe generic version of KEY_LAST, KEY_FIRST.
