Does flirc able to do Fn functions?

Recommended Posts

Fn key is not a modifier key in the same sense as other modifier keys like ctrl, alt, shift. Normal modifier keys are being processed on the USB host device (your computer or other device you connect the keyboard or Flirc to). When you press for example ctrl + F, the keyboard sends hid code for key F with modifier code for ctrl.

Fn key is being processed on the controller which is built into the keyboard. When you press Fn + F12, the keyboard doesn't send hid code for F12 key anymore. It sends something that's dependant on the keyboard itself (different makers and models have different Fn functions on different keys).

In your case, the Fn + F12 is the media key for Play/Pause. You can find it in Flirc GUI in Media Keys controller.
