I notice in Leopard they have the exposé application and now on the new keyboards they have a dedicated exposé button. However exposé has many different options. Desktop, All windows, application windows. So what happens when you press the new exposé button on the keyboard, which function does it do, can you get the other options through modifiers. Same questions applies to the exposé application in Leopard.
