To get to the point quickly,I put my headphones down on my table alot and sometimes it lands on my keyboard and it's small Iron support things lie on the keys untill I come back to pick it up again. this started happening where my headphones stays on a certain key that activates this shortcut. I fixed it once where I had to hold something down for a certain period of time or there was some kind of key combination that fixed the problem,Its not in the keyboard,As the Backspace and the Enter key worked for a whole month untill this happened today again. Moral of the story is that I get a Headphone-Holder. But I still didn't manage to fix the backspace problem.
