The command bar combines the functionality of the menu bar and toolbar in one control. The menu names on a command bar represent the main categories of commands that an application provides. Selecting a menu name from the command bar opens a menu whose menu items correspond to the commands in a specified category. For example, a command bar might contain a File menu name that, when selected by the user, activates a menu with menu items such as New, Open, and Save.
