ABSTRACT:
A multimedia keyboard structure which includes a standard keyboard having a control key pad having a set of keys for cursor, number, screen scroll and multimedia function controls. The control key pad is connected to the scan matrix formed by the I/O lines of the microprocessor of the internal circuit structure of the keyboard. The scan code of Num Lock or Scroll Lock is adapted to match Win 95's register in testing the flag bit of Num Lock or Scroll Lock and judging its flag bit through a driver so that the job of code converting can be executed. The operator is allowed to directly control the control key pad and to monitor the operation through a display screen to which the standard keyboard is connected by means of employing the function provided by WindExec O of Windows API to the path of the file and the file index of the application program.
