Issue with PgUp and PgDown not working, potential fix.

Hello everyone. I just want to offer a potential fix for the PgUp/PgDown not working when you want to switch to other controllers in the game settings. The fix is simple: Go to search and get On-Screen Keyboard on and use the PgUp/PgDown from there. It works. 

Or, a much harder fix if that still doesn't work or you don't like the solution, buy a keyboard that doesn't have that little button called FN (Function Key). 

Thought, I would highly suggest the first fix with the On-Screen Keyboard since it doesn't require buying anything. 

(I know there may have been other solves for this issue and that this issue is years old, but I thought I'd help out anyone that still has the issue, like me.)
