Hello,

on my notebook dell-wmi kernel driver generates some scan codes=20
when I press some of Fn key combinations. Now all these scan=20
codes are mapped to key "prog3". I would like to add some actions=20
for these Fn key combinations, so what do you think? Which key=20
codes should be assigned for these scan codes? Note that these=20
combinations are not special (and labeled) as other (like Fn+F11=20
=3D play/pause) and seems like windows does not recognize them.

Matthew, you are author of dell-wmi driver, do you know if there=20
are some other secrets key combinations? And why first 10 Fn key=20
combinations generate scan codes?=20
