I've fixed the mapping for this (undocumented) virtual key code, so hopefully
this works correctly now. I've uploaded a snapshot at [1]
I can't test this as the keyboards I have with an Fn key don't generate a
separate keypress for that, apparently Lenovo laptops are special in this
regard :-), so please let me know if this works.
