If there are still windows that have not been minimized then the frontmost of them will become active. If you click on the tab corresponding to the active window then that window will be minimized. Whenever you start an application you will see a new tab in the Task Manager showing the icon of the application and the title of the window that was opened. You can even have several copies of it in various places. For example, you could add a new panel to (say) the top of the screen and place the Task Manager there or you could place it on the desktop if you wish. The Task Manager is actually a widget, which means that you can place it anywhere. If the window of an application has been placed behind other windows or if it has been minimized you can bring it up and ready to receive input by clicking its tab in the Task Manager.

It is located in the middle section of the Panel. The Task Manager provides easy access to running applications. Task Manager widget in panel showing three applications.
