Hi Pete
Thanks for the reply. I started to play with " XWP Keyboard, Function Keys, RightMouseClick and select New Function Key".
My issue seems to be:
1) For the Thinkpad L420 (Internal Keyboard). I have four special buttons on the right (Mute mic, vol+, vol-, Mute). All, with the exception of "Mute Mic" are recognized, which is good.
2) On the same Thinkpad L420, I have the special Fn keys for "Petsis, lock, battery, sleep, wireless?, camera.... etc. Those keys should be pressed with the Fn key, but the FN key gets recognized (0x89 (137) ) . the special Fn keys only get recognized for F9 = Despl, F10 = Numloc, F11 = Pause, Insert=PrintScreen, Esc=Inter, and the special ones on the arrows work.
Is there something else that can be done for the one missing? F2 to F8 ?
Wait, If I turn "PSD=ACPI.PSD /NOACPI" I get the brightness up and down buttons (del and home) working with Fn with the screen brightness and the XWP Key Mapper. And also all the missing Fn keys, including the "Mute mic" button.
I will try some other USB keyboards withe special keys.
Regards
