To remove an item, enter edit mode by clicking the Edit button, click on the item you want to remove to select it, and press the Remove Button. Alternatively, you can choose Remove from the File menu. You can also remove an item while in edit mode by simply dragging it away from the Overflow window. When you release the mouse it will vanish with a poof. A final way to remove an item is to control-click the item and choose the Remove menu item.
