Abstract: A method and a computer system for keystroke event notification are provided. The method includes a number of steps. A keyboard controller scans a number of keys contained in a keyboard. The keys include at least one pressure-sensitive key and at least two key-functions are assigned to each of the at least one pressure-sensitive key in response to a pressure applied on the pressure-sensitive key. When one of the pressure-sensitive keys is scanned by the keyboard controller, the keyboard controller measures the pressure applied on the pressure-sensitive key. The keyboard controller uses at least two pressure thresholds to determine a level of the measured pressure. The keyboard controller controls a storage device containing a source code of a basic input/output system (BIOS) to deliver a keystroke event on the basis of the determination result, so as to activate one of the key-functions of the pressure-sensitive key.
