What's new in the Ribbon UI, other than just appearance? Commands are arranged in groups on tabs—that's the Ribbon—and although the arrangement is intuitive, it's quite different than the traditional menu scheme that users are familiar with. There's no Tools menu, for example, and all menu functions have been redistributed to various tabs on the Ribbon. Some Ribbon tabs are contextual, meaning that they appear only when needed. The Picture Tools tab, for example, appears only when you select a picture in the document. Another example is there's no View, Toolbars menu because this functionality is integrated in the Ribbon, as well as the new view buttons and zoom slider that display in the lower-right corner of the window. The right-click context menu now contains a subset of formatting commands from the Ribbon so that you can make common changes without having to move the mouse up to the Ribbon. Commands that relate to the document as a whole or to the application's configuration are now found in the menu revealed by the Office button in the upper-left corner of the application window. Look there for many commands in the File and Tools menus in earlier Office versions. You customize the Ribbon differently than you customized your toolbar in the past. To customize the Ribbon, you customize the Quick Access Toolbar that's located, by default, next to the Office button and is available regardless of which tab or section of the Ribbon you're currently viewing. The Quick Access Toolbar is an ideal location to place commands that you use frequently. The drop-down arrow at the end of the Quick Access Toolbar lets you configure its placement above or below the Ribbon, customize the commands on the toolbar, and minimize or restore the Ribbon. Minimizing the Ribbon lets you free up real estate in the application window. One of the more eye-catching features of Office 2007 is Live Preview, which dynamically applies changes as you hover over commands, previewing what the document, worksheet, or presentation will look like if you click the command. No more “experimenting” with formatting—it happens in real time!
