You cannot delete or replace the ribbon with the toolbars and menus from the earlier reports versions. However, you can minimize the ribbon to make more space available on your screen. When the Ribbon is minimized, only the tabs display.
To keep the ribbon minimized, click the drop-down list next to the Quick Access toolbar and select Minimize the Ribbon. To use the ribbon while it is minimized, click the tab you want to use and select the option or command you want to use. After you click the command, the ribbon returns to a minimized view.
To restore the Ribbon, click the drop-down list next to the Quick Access Toolbar and clear the Minimize the Ribbon check box.
To toggle between full and minimized view, double-click the name of the active tab or press Ctrl+F1.
