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?

Did you place the `AutoHotkeyRemoteControlDLL.ahk` in the "C:\Users\YOURACCOUNTNAME\Documents\AutoHotkey\Lib" directory? — Robert Ilbrink, Mar 09 '13 at 12:08
first you can try sniffing whether the keyboard does transmit the `Fn` key or not. If not, then any driver or remapper won't work. Article http://julien.danjou.info/blog/2012/logitech-k750-linux-support can guide you, they used Wireshark under Windows with k750. — miroxlav, Mar 18 '14 at 14:43

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
