Setting Up Your PowerPoint Environment
The Save, Undo, and Redo commands appear by default on the Quick Access toolbar. You may want to add other commands to make using specific PowerPoint features more convenient for you.
The new tabbed Ribbon system replaces traditional menus in PowerPoint 2007. It is designed to be easy to use and responsive to your current task; however, you can choose to minimize the Ribbon if you would prefer to use different menus or keyboard shortcuts.
You can also minimize and maximize the Ribbon by right-clicking anywhere in the Ribbon and selecting Minimize the Ribbon in the menu that appears.
