15 simple, secret Windows tips and tricks designed to save you time | PCWorld. You are probably familiar with the keyboard alternatives to Right click and Copy or Paste. Since my right hand is always on the mouse, it is easier to highlight text or whatever, and right click to copy and paste. However, you can also use the Control key (Ctrl) with C or V to copy and paste. However, what if you miskey something, or do something stupid (Yes, you do sometimes) and make a copy of a list of files by mistake or some other dumb thing. Use the Ctrl key along with Z and, presto, the last action disappears. All is right with the world.
