A-6 Setting Up a Healthy Work Environment
Adjust the keyboard height so that your elbows are near your body
and your forearms are parallel to the floor, with your forearms resting
on either armrests or forearm supports, in the manner described
previously. If you do not have armrests or forearm supports, your
upper arms should hang comfortably at your sides.
Adjust your keyboard slope so that your wrists are straight while you
are typing.
