ToolBar 
    A horizontal or vertical bar, most often used to hold Buttons. Status Bars (at the bottom of many application windows) also use ToolBar.
If there are too many items to fit in the available space, a pull-down button appears, giving access to the remaining items. At time of writing, this button hasn't been implemented.
