The infamous FN key (not on laptop), how to detect / send?

Recommended Posts

Hi all!

First of all, I searched a lot on the forum and on google, but I couldn't find an answer due to laptop-related questions or similar.

Before starting the question: the aim is to remap my GXT850 keyboard FN key, which is not software controlled (is a plug and play keyboard). I'm not here asking for a keylogger, I know how to do one by myself and I don't need to ask it here 😂 Jokin', I'm just trying to get this FN key code if I can :) Way more difficult!

So far I have some ideas and no clue on where to start from.

I would like to detect the pressed key on the keyboard without knowing the key code, the aim here is to find which code is this FN key so that I can use _IsPressed after this.

Actually the keyboard is plug and play, so I bet that the FN key is somehow "standard" because it's recognized by Windows without any software or customized driver support.

When I press FN+F11, for example, utilman shows up.

This lead me to think that the FN key here is somehow standard and therefore emulable.

That's why I was thinking of intercepting any pressed key, so I can press FN and I can get the code.

Thank you for any tips on how to do it, also other ways to do it are welcomed!

Tested it with my keyboard hook and the FN key is not intercepted.  Seems that the key is totally internal to keyboard and is never sent to computer.
