ABSTRACT:
A cellular telephone with a pointing device that facilitates operations for line scrolling and page scrolling, in which the moving speed of a pointer can be controlled with respect to each on-screen display. The pointing device includes a pointer-operating button having a range of sliding movement. The pointer-operating button can be pressed down and slide within the sliding movement range by single finger operation, and is located in the center of the sliding movement range when not being operated. The pointer-operating button returns to the center position when released in sliding operation, and returns to its former condition when released from the pressed state in pressing operation. Besides, the sliding movement range defines a pointer movement frame. A switch to line scrolling mode or page scrolling mode is made by bringing a pointer into contact with the top edge or the bottom edge of the pointer movement frame. The moving speed of the pointer can be controlled with respect to each on-screen display.
