Positioning the keyboard
Make sure the keyboard height is comfortable for typing.
When you type, keep your forearms parallel to the floor and
relax your upper arms. Your elbows should form a 90-degree
angle.
Type with a light touch, keeping your hands and fingers
relaxed. Your wrists should also be straight.
If your computer came with a wristrest and you choose to use
it, do not rest your hands on the wristrest or desktop while you
are typing. Instead, use the wristrest only when resting. If you
prefer not to use the wristrest, you may remove it and use the
keyboard without it.
Positioning the mouse
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.
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.
