It includes a module that shows you statistics about the student's progress and the number of mistakes they make.
The lessons have been prepared to teach you how to type using the layout of two different keyboards: QWERTY and Dvorak. MasterKey lets you use the lessons provided with the program or you can use any other plain text file.
Throughout the lesson, there is a graphic that shows you where you should place your fingers on the keyboard.
MasterKey also allows several users to take advantage of the program, either on the same computer with different accounts, or through a local network.
For Mac OS X 10.3 or later. OS X Jaguar (10.2) users must download MasterKey 5.2.5.
Some functions are disabled and a message invites you to register the program at the beginning and end of each lesson.
