Abstract
A mobile terminal is provided that includes a touch input unit and a display. A method of operating the mobile terminal includes operating the touch input unit of the mobile terminal in a normal mode, detecting a first multi-touch signal from the touch input unit, switching the touch input unit from the normal mode to a direction input mode in response to the first multi-touch signal, detecting a second multi-touch signal from the touch input unit while the touch input unit is in the direction input mode, determining a direction represented by the second multi-touch signal based on the tap signal, and scrolling at least one object displayed on a screen of a display of the mobile terminal in the determined direction. The second multi-touch signal may include a tap signal.
