When you press ctrl alt f1 ect you get a terminal indepenant of X and is wonderfull if you know what your doing, but say my mum accadentally presses ctrl alt f1. Not knowing really what she is doing or the cat lands on the keyboard and puts it into a terminal. She would think the computer is broken and be very confused on how to fix it I think we should put a discription as to what it is and how to get back to X
