Only people who studied application development or those who are very good at computer science can know how the keyboard and mouse run on Java.
KeyPlayer is a program to test how the mouse and the keyboard function. Each event is displayed in a window, i.e. each time you use the keyboard or the mouse, a detail of these events is generated. A minimum of DOS command is necessary to install the software. KeyPlayer requires the latest version of Java to run.
An ideal software for those who would like enlarge their knowledge in computer science.
