Switching Autohotkey Fn keys on a Logitech k750 keyboard

Question

I searched googled, read forums, but didn't understand this. Tried "Secret key Fn" http://www.autohotkey.net/~daonlyfreez/tutorials/3p/Veil/fnkey.htm But stuck in AutoHotkeyRemoteControlDLL.ahk, which does not respond to 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 many keyboards do not implement it as a regular key, but as a modifier that simultaneously changes the key messages of other keys.

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

Push F1 down - Windows gets F1 code down
Push F1 Up - Windows will Receive F1 Extension Code

Press Fn down - Windows won’t receive anything. Press F1 down - Windows receives media ▶ down code
Press F1 up - Windows will receive a multimedia file ▶ up code
Press Fn up - Windows will not get anything
