Ctrl-Z

Ctrl-Z allows you to undo your last action.Yes I have I always wish I had Ctrl-Z because its more easier to fix your mistakes that had been wrong.I think that it would  be weird because I don't like things making me talk over and over again. I would use Ctrl-Z for in real life to help me find my mistakes and fix them to make a better person and not imagine that bad things that I did.
