Contextual tabs and menus appear when an object is selected. These contextual tabs / menus contain information or options pertinent to that object only. In PowerPoint 2007/2010, these contextual tabs are very much in view, unlike earlier versions, where these commands could be difficult to locate. This feature is an updated version of the shortcut menus used in earlier versions, although these menus are still available in some situations.
These contextual tabs do not appear unless they are relevant to the selected object.
