Back to Top helps navigate long pages. Go to the top or bottom of a page with a single click. Using right clicks and control clicks you can scroll a page or line at a time. Version 4.0 allows you to map the clicks any way you like. With drag and drop, the statusbar icons can be ergonomically arranged.
