HP Omen with keys P1 through P6. How to get keys connected to them?

The keys are supposed to respond to mouse events. Under windows the keys report the same as the keys to their right (so P1 -> ESC ... P6 -> Control)

These commands report nothing (used after a sudo -i:

cat /dev/input/mice | od -t x1 -w3 
xinput test-xi2 --root 
showkey --keycodes
acpi-listen

I also tried with mev (mouse version of xev) from gpm.

Is there a way to get these keys to react to a control-shift-something so I can attach an event?

This system also has a "omen key" (in between the delete and printscreen).

showkey --keycodes 

shows
