ScrollJump enables users to use option plus the 5-way navigation control to jump to the top or bottom of a scrolled display. It was originally created to operate in Blazer for the Treo 650 (another program did not work properly) but can be turned on in other programs as well. The degree to which it will be useful elsewhere depends on the program.

In Blazer, the default behavior for the up and down keys is to scroll page by page. However, users often find themselves at the bottom of long pages when the site navigation controls are located at the top. Using the up key, the only way to get back to the top is to scroll through the whole page again. ScrollJump allows users to return to the top, or jump to the bottom, in one simple action. ScrollJump has been tested in Xiino as well.
