The user can drag an object to the Trash when it is closed. (The user can also select the object and choose Move to Trash from the Special menu.) Notice that the Trash behaves like a standard container in that it accepts objects while it is open or closed and its contents are revealed by opening it.
To permanently delete an object that has been moved to the Trash (and reclaim its disk space), the user chooses Empty Trash from the Special menu.
