Toolbars, menu bars, and shortcut (right-click) menus are combined into a single functionality, called "toolbars" in the user interface, and "command bars" in Visual Basic for Applications. Command bars can be one of three types: menu bar, toolbar, or pop-up menu. The pop-up menu type includes drop-down menus on menu bars (such as the Edit menu) and shortcut (right-click) menus. Each type can include built-in and custom commands.
