With IntelliPoint mouse software, you can customize the unique features of your Microsoft mouse to fit your needs. Each mouse button - including the wheel button - can be reassigned to perform a command or keyboard shortcut such as Print, Close, or an application-specific function. You can also modify mouse settings, such as pointer speed and horizontal scrolling. IntelliPoint also includes the Magnifier, which makes it easier to read a small block of text on a Web page or to enhance a photo. IntelliPoint software even offers biometrics support for advanced identity management. If you have a Bluetooth mouse, you will need to have Windows XP with Service Pack 2 installed.
