A corner sleeve? Why is it used on an L-shaped desk?

A corner sleeve offers extra desk room to lift the keyboard tray for you. The desktop will stop a tray from lifting without a sleeve. Even if you never plan to lift your tray above desktop level, comfortable typing and mousing can be interrupted by the bottom of the desk.
