A keyboard can be dangerous if used incorrectly.
Please follow these rules:
One finger per key (
Hint: Are your fingers smaller than normal? Wear 10 thimbles!)
One key per finger (
Hint: Having trouble? Aim for the center of the key)
Use the correct key (
Fact: The computer is not able to guess that you meant to enter another key than you have pressed)
Don't experiment with your keyboard (
Fact #1: Every 5 seconds, almost 3 million people accidentally press ctrl-alt-backspace

Fact #2: Pressing the "Sys Rq" button will often trigger viruses written to target curious keyboarders)
