My left arrow key, delete, insert and print screen keys are highlighted brighter than the other keys all the time. The left arrow key doesn't work as intended, delete behaves like tab, print screen puts my browser in full screen while simultaneously turning up my volume.

I've tried uninstalling keyboard drivers, nothing changed. And this shitty keyboard doesn't have an instruction manual. Unplugging and plugging in didn't work either.

It's an MKA11R Raptor.

Anyone know how to restore them to their normal behaviour? Thanks.
