Tool Box
A Tool Box or Toolbox is a window or pane that contains icons and buttons that are tools in the program. The tools are for quick access to common operations. A Tool Box may float freely or may be docked in the main window of the program. For example, Microsoft Paint contains a Tool Box including the pencil, eraser and other common tools.
Often many programs that have a Tool Box allow the users to display or hide the Tool Box through the View drop-down menu at the top of the window.
