I have an Lenovo T60 and wanted to see how to get functionality with the back/forward buttons as well as the center scroll button. I've looked under System>preferences>keyboard>layout, but lenovo wasn't one of the mentioned manufacturers, and under IBM were laptops from many, many years ago (i remember from the days of my IBM 760el...)

How can I get these buttons to function in ubuntu? In firefox when i press the scroll button a window comes up saying "the url is not valid and cannot be loaded" so its obviously mapped to do something, though I don't know what. Nothing happens when pressing the back/forward buttons.
