So recently I don't know what keys I perhaps pressed, but suddenly my keyboard got all wierd, every key literally is a short cut now. Before, it used to be the windows logo + L is locking the computer, now just pressing L is locking. Just pressing E is opening hardware open, backspace is bring up the toolbar ect. Ctrl-alt-del no longer works either, and I cannot switch between programs or type (i'm using another computer to ask this question). Whats happening?
