The Mouse Bridge is an inexpensive solution that places the mouse closer to the main portion of the keyboard so that arm extension is minimized while mousing. The Mouse Bridge is designed to straddle the numeric keypad portion of the keyboard so you can more easily reach your mouse. This is an ideal solution if you mouse with your right hand, use your number pad infrequently, or if you have limited space for mousing. There are several models available depending on the size and shape of your keyboard and how much mousing surface is needed.
