simulate an arrow key on a keyboard

There’s a setting that allows you to simulate arrow key presses. I enable this switch and assign the left and right arrow keys to the game “RUST.” But nothing happens. Could you please tell me what I’m doing wrong?
And if I open Notepad, should the cursor move through the text when I rotate the wheel in simulation mode?
