Abstract

An information processing apparatus includes an input means having a plurality of switches arranged thereon, the direction of the sequential actuation of the switches is detected to determine a scrolling direction of movement of information. Marks are provided on a display to indicate the direction of scrolling. The display of information is controlled in accordance with the direction of movement of the information. Scrolling the information is inhibited when the direction of actuation of the switches conflicts with a predetermined scroll direction. Scrolling velocity may be controlled by the speed with which switches at the position of each mark are actuated.
