W Make sure the keyboard height is comfortable for typing.
W When you type, the keyboard should be positioned so
that your arms are relaxed and comfortable, and your
forearms are roughly horizontal. Your shoulders should
be relaxed and not hunched up.
W Type with a light touch, keeping your hands and fingers
relaxed. Your wrists should also be straight.

W Position your mouse on the same surface as your
keyboard so that they are at the same level. Allow enough
space so that you can use your mouse without stretching
or leaning over.
W When you use the mouse, hold it lightly with all your
fingers and click gently. Move the mouse with your entire
arm instead of only using your wrist.
