I know that there is an "icon" or application to show either your Dashboard or "Expose" your windows, but I'm looking for something that will display my desktop. What I mean by that is doing what 3 fingers down on a MacBook Pro does. I understand that I can mark such option on my keyboard, or assign a button on my external mouse to do it, but I'm looking for something similar to "Expose" found in Utilities and "Dashboard" found in Applications. An icon, an application, something to click. Any help?
