On a latitude D630 evtest says, for the Fn+Left combo:
Event: time 1237140710.654713, type 4 (Misc), code 4 (ScanCode), value 93
Event: time 1237140710.654727, type 1 (Key), code 193 (F23), value 1
Event: time 1237140710.654730, -------------- Report Sync ------------
Event: time 1237140710.654733, type 1 (Key), code 193 (F23), value 0
Event: time 1237140710.654735, -------------- Report Sync ------------
You might want to run evtest on you model. Source code is attached (I
can't find the original source of this file but I've seen it flying on
some MLs).
