How do I set tabs in Microsoft Word?

The Ribbon, a panel that houses the command buttons and icons, organizes commands as a set of Tabs, each grouping relevant commands. Each application has a different set of tabs which expose the functionality that application offers. For example, while Excel has a tab for the Graphing capabilities, Word does not feature the same. Instead it has tabs to control the formatting of the document. Within each tab, various related options may be grouped together. The Ribbon is designed to make the features of the application more discoverable and accessible with fewer mouse clicks as compared to the menu-based UI used until Office 2003.
