ABSTRACT:
The data display-controlling device and method includes a control key used for reducing the speed at which data is displayed on a display unit. If the control key is depressed, this condition is detected by a central processing unit (CPU). Upon detection of the depression of the control key, the CPU reads current time from a timer, and determines whether a predetermined time has passed from the depression of the control key. If the predetermined time has not yet passed, the CPU executes the operating system program, and if the predetermined time has passed, data to be presented is supplied to the display unit.
