I have found “a solution” to the Problem.
For me, I want to have Pos1, End, Page Up and Page Down on the top right.
so I created a AutoHotKey script that re-maps the keys.
no the problem is that the F10 alternate Fn function is directly forwarded to the Bios making it impossible to easily remap. BUT its possible to remap F10
So here my dumd/genius Idea: completely inverse all F and Fn keys.
For example F1 maps to Volume Down and Volume Down Maps to F1.
Then use fn lock to inverse Fn key behaviour.
its not completely perfect as you need to use Fn to change screen brightness but it works
if you are like me and almost never use F-Keys, this might be a solution.
here my AutoHotKey Script:
#Persistent
#InstallKeybdHook
; KeyHistory
+F12::KeyHistory ; Press Shift + F12 to display the key history window
; Invert Fn Keys to F-keys
Volume_Mute::F1 ; F1
Volume_Down::F2 ; F2
Volume_Up::F3 ; F3
Media_Prev::F4 ; F4
Media_Play_Pause::F5 ; F5
Media_Next::F6 ; F6
; F7
; F8
LWin::Return ; F9
; F10 (Flight Mode button has no key code)
PrintScreen::Home ; F11
Launch_Media::End ; F12
; Map Fn Key onto F-keys
F1::Volume_Mute
F2::Volume_Down
F3::Volume_Up
F4::Media_Prev
F5::Media_Play_Pause
F6::Media_Next
F7::F7
F8::F8
F9::Home
F10::End
F11::PgUp
F12::PgDn
