Next,when we replaced the mouse for the non-profit I work with, I talked the director into the Logitech Cordless Wheel Mouse. It also has great functionality and the advantage of no cord to tangle or tempt the resident cat. The same Cyberjump choice is available, also. A single click of the center wheel opens a little macro allowing back,forward,refresh,stop,bookmark and Web Wheel help at a click. Five URL slots are also offered, which are programmable easily.
All buttons are programmable for custom purposes on the mouse.
The scroll button saves a lot of wrist motion and fishing for on screen scroll bars. Scrolling lines and speed can be customized also. The longer design helps keep the wrist off the edge of a desk as well. Wheel Mouse works happily on the left or the right of your keyboard, and fits left or right hands equally well. As most lefties know, this is not always the case,and it's especially nice if you have left and right handed users of the same computer station.
