Keyboard demon

Greg is sitting at his computer browing his favouriye website and a demon pops out from behind his keyboard and proclaims "for I am the almighty keyboard demon! here to steal all your keys" Greg jumps back out of his seat like a shot! Taking advantage of this, the demon grabs the keyboard and steals the top left key then disappears back behind the keyboard. Puzzled, Greg lifts the keyboard up and asks the Demon, "If you are almighty? why did you only steal the top left key?" The demon turns to him with a evil smirk on his face and proclaims, "Now there is no escape!"
