Does anyone know if there is a way to catch the other mouse buttons that some mice have?

Basically, I'm developing an application in Flash (which is going be to be EXE'd using mProjector) and the application needs to mimic a web browser's behaviour so I wan't the user to be able to browse forward and back with the methods they're used to using such as backspace on the keyboard and the navigation buttons on the mouse. The keyboard one is easy, cos I use a Key listener, but anyone know what to do for the mouse buttons???!


Thanks
