Frequent computer users are required to use proper keyboarding techniques to develop optimal keyboarding speed and accuracy. In addition, acquiring these techniques will also prevent the development of repetitive stress injury. We should watch how we rest our fingers on the keyboard. The wrist should be kept straight and off the keyboard. For the numeric keypad, the right index finger controls the numbers 7, 4, 1 and the Num lock while the right middle finger controls the numbers 5, 2, and 8. Right thumb controls 0 and the right pinky controls the + and – sign.
