You can add your favorite—or most commonly used—commands to the Quick Access Toolbar in the 2007 Microsoft Office system, so that these tools are always easy to find. You’ll find the Quick Access Toolbar next to the File or above the Ribbon.
The default commands on the Quick Access Toolbar are Save, Undo, and Repeat. You can add your most-used favorites by clicking the expandable arrow to the right of the Quick Access Toolbar to open the Customize Quick Access Toolbar menu. Here, you can select the set of commands that you want on the Quick Access Toolbar.
To add commands that aren't on the list, click More Commands. If you're adding a lot of new commands to the Quick Access Toolbar, use the Customize menu and click Show Below the Ribbon. This will move your Quick Access Toolbar to below the Ribbon to give it more room to expand.
