Is there a way to make Fn+F3 do what is suggested by its icon? I think it should send KEY_SWITCHVIDEOMODE defined in /usr/include/linux/input-event-codes.h file, but I can't find anything similar in include/keycodes.h.
EDIT:
OK, I 've figured it out. First I've changed keyboard firmware so it would send F15 when Fn+F3 is pressed, it will send 6a, then I've created file /etc/udev/hwdb.d/90-usb-kbd-custom.hwdb with contents:
It will translate F15 to KEY_SWITCHVIDEOMODE (but first I had to run: sudo systemd-hwdb update).
Now Fn+F3 works like Meta+P (in KDE).
I've tried with 0xBF because it was not used, but it was not send, either.
