Microsoft's Natural Ergonomic Keyboard 4000 was designed for the reduction of carpal tunnel syndrome symptoms. When in use, wrists are able to rest against a plush surface at a natural angle. The keyboard’s curved key bed, ergonomic arc, and reversed slope reduce tension buildup. The device also allows for customizable user access with "hot keys". For example, the Zoom Slider, located in the middle of the keyboard, lets a user zoom in and out of the screen with the touch of a finger.
