Proper positioning of your keyboard includes the following:
Positioning the keyboard:
Position the keyboard directly in front of you. This makes it possible to type with your shoulders relaxed and your upper arms hanging comfortably.
Adjusting the keyboard height and slope:
Adjust your keyboard slope, so that your forearms, wrists and hands are in their neutral comfort zone.
Aligning the mouse and keyboard:
When using a mouse, position the device immediately to the right or left of your keyboard. Avoid positioning the device too far from the side of the keyboard or toward the keyboard's back edge.
