By default, the installation program will assume that you have a two-button mouse and set up the emulation of the third button. The installation program will automatically determine which interface the existing “mouse” device is connected to.

If you want to specify a different mouse type, you should select an appropriate one from the list. If a type different from the default one is chosen, the testing screen will be displayed. If the mouse does not work, you should go back to the previous screen by pressing the Space or Enter button and select a different option. In some cases (for instance, with a wheel mouse), in order to test the mouse it is necessary to press all the buttons, scroll the wheel and move the mouse.
