Abstract

A method of scrolling items at a touch screen display is disclosed and may include detecting a first scroll command, scrolling at a first scroll speed, and zooming out to a first zoom level, wherein the first zoom level is associated with the first scroll speed. The method may further include determining whether a second scroll command is detected and scrolling at a second scroll speed if a second scroll command is detected.
