1. A method of controlling a portable electronic device having a touch screen display, the method comprising:
- providing a graphical user interface on the 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.
