Driving with a Computer Keyboard
“Imagine trying to drive a car using a computer keyboard. The four arrow keys are used for steering, the space bar for braking and the return key for accelerating. To indicate left you need to press the F1 key and to indicate right, the F2 key. To sound your horn you need to press the F3 key. To switch the headlights on you need to use the F4 key and the F5 key for the windshield wipers. Now imagine as you were driving along a road a ball is suddenly kicked in front of you. What would you do? Bash the arrow keys and the space bar madly while pressing the F3 key?”
