摘要：
A method of controlling a portable electronic device that has a touch screen display includes providing a graphical user interface on a touch screen display, detecting a touch event at a first location on the touch screen display, providing a navigation indicator in the graphical user interface in response to detecting the touch event at the first location, and in response to detecting movement of the touch event from the first location to a second location while touch contact is maintained on the touch screen display, changing the position of the navigation indicator in the graphical user interface by a distance that is greater than a distance of movement of the touch event on the touch screen display, a direction of change of position of the navigation indicator is based on a direction of movement of the touch event on the touch screen display.
