Hi—Am trying to map Fn to Fn Lock in order to trigger the built-in Mac OS keypad across 7-8-9, u-i-o, j-k-l and m, but nothing seems to be working. Setting Fn to Fn Lock shows the lock notification on screen, but only when triggered by the onboard keyboard. The external Matias does nothing. I even edited the private.xml (below) to bring the option up front, but still checking the box does nothing when pressing Fn on the Matias. I have confirmed Fn works on it just fine, as holding it down and typing those keys does in fact give the number pad settings. Thanks!
