Manufacturer description
The Kensington Orbit Trackball Mouse (K75327WW) replaces the mouse-and-mousepad routine with a stationary optical trackball you steer using your thumb and fingers, so your wrist stays planted instead of sweeping across the desk. The defining feature is the Scroll Ring encircling the ball: rotate it to move through long web pages, spreadsheets, and documents without hunting for a wheel. The ambidextrous shape works identically for left- and right-handed users, and the detachable wrist rest cushions and cradles your hand during long sessions at the computer.

Frequently Asked Questions
Does the Kensington Orbit Trackball work for left-handed users?
Yes. The Orbit uses an ambidextrous design that Kensington states works equally well for both right-handed and left-handed users, so the shape is symmetrical rather than contoured to one hand.
How do you scroll on this trackball?
A Scroll Ring encircles the ball. You rotate the ring with your fingers to move up and down web pages or documents, so there is no separate scroll wheel to reach for.
Can I reprogram the buttons?
Yes, using Kensington's free downloadable TrackballWorks software. It lets you assign a wide variety of program functions to each of the 2 buttons and adjust cursor and scrolling speeds.
Is the wrist rest removable?
Yes. The wrist rest is detachable, so you can use it to cradle your hand in an ergonomic position during long sessions or remove it for a smaller desk footprint.
