Windows 10: Keyboard keys map to functions other than letters?

Until a few minutes ago everything was fine. Suddenly, I'm not able to type anything on my Windows PC's keyboard anymore. Instead, keys are mapping to other functionalities. For example, the up and down arrow key change brightness; pressing "R" takes a screenshot; pressing "ctrl" behaves like a right click. I think I might have inadvertently pressed some keyboard combination. The TouchPad works as usual. No clue as to what is happening; any help would be appreciated. Thanks!

Keyboard Volume Keys not working while in-game

I happen to have used the Tt Challenger Pro keyboard in the past, and the volume keys worked flawlessly in every game, so it's indeed a weird problem. I would suggest the same thing sneekypeet suggested, using the keyboard software and assign this function to a hotkey, but you said that didn't work either, so yeah...
