Windows hotkeys: how to simulate pressing another key?

Question

Keyboard

I want to create hotkeys to simulate keystrokes on the keyboard.
Let's say pressing "FN + J" simulates a down arrow "↓", and "FN + K" an up arrow "↑".
What do you say?

Answer 1

I don't think it will work.
Quote from the forum:

Fn is purely a hardware key on laptops.
As far as I know, it works regardless of OC.

Extract from wikipedia :

However, due to the fact that the OS does not know about the presence of the Fn key, it usually cannot be assigned a different function through the software, unlike all other standard keys.

Answer 2

This bios either allows or not (out of the box)

Answer 3

Fn is a very mean key. As already mentioned above - it is hardware. But that is not all. On many laptops and/or keyboards, fn is not just a hardware fn, but it also generates a key combination rather than a specific media key. How to solve this problem? I have found two solutions for myself:
Naturally, this does not solve the problem, but it allows you to mitigate the consequences, as in my case.

Answer 4

Can.
