The Keyboard and Mouse The keyboard and mouse at a computer workstation are often positioned incorrectly. They are typically placed wherever there's room for them, regardless of comfort. Following the guidelines below will increase your typing comfort and help you avoid possible long-term conditions affecting your wrists and arms. Arranging your keyboard and mouse When you use the keyboard, your wrists should float comfortably above the keys. They should be straight and relaxed. Use a desk or table that is preferably about 28" high- don't use it in bed, on the floor, on on your lap.   If they are not, adjust the height of your keyboard until your wrists are parallel to the floor.  Try sloping your keyboard downward toward the back. Use a small notepad to prop up the front of your keyboard. Avoid raising the keyboard "feet". A wrist rest or padded support will help your wrists feel relaxed when you are not typing. Wrist rests are designed to support the heel of your hand, not for resting your wrists themselves. Place the wrist rest so it is level with the top of your keyboard's space bar. Mouse wrist rests are also available.  If you use a keyboard tray, make sure that both the mouse and keyboard fit in the tray. Your mouse should be within easy reach, on the same level as the keyboard. Don't reach for or tightly grip your mouse. Learn the shortcut keys that can replace mouse actions in the applications you use most frequently, and use them instead of your mouse to relieve repetitive clicking. If your wrists are still not straight, check your chair height. Make sure your feet remain on the floor or on a footrest.  If you have trouble with a regular mouse, try using a trackball or touchpad instead. There are also "ergonomically designed" mice that are larger and shaped to fit the hand better. These are available in many computer stores.
