Autohotkey Fn key remapping on Logitech k750 keyboard

Question

I've googled, read forums but unsucceed in this. Tried "Mystery of the Fn key" http://www.autohotkey.net/~daonlyfreez/tutorials/3p/Veil/fnkey.htm But stucked at AutoHotkeyRemoteControlDLL.ahk, that doesn't react on my Fn key on all devices (1-5 HID, 6-9 Keyboard, 10-16 mouse).

Any suggestions?

Answer 1

The problem with the Fn key is, that a lot of keyboards don't implement it as normal key, but as a modifier that changes the key messages of other keys pressed at the same time.

So here is an example scenario of how Windows could see your input:

Press F1 down - Windows receives the F1 down code
Press F1 up - Windows receives the F1 up code
Press Fn down - Windows doesn't get anything
Press F1 down - Windows receives the media ▶ down code
Press F1 up - Windows receives the media ▶ up code
Press Fn up - Windows doesn't get anything
