For many people, the ribbon interface used in Microsoft Office 2007 is a great
step forward, while others find it overwhelming. If you fall into the latter category,
you’ll be happy to know that the ribbon can be temporarily hidden to provide you
with a larger working area.
It’s also worth noting that the ribbon can quite easily be hidden by accident, so if this has happened, use this tip to help find it again. Click the down arrow icon at the end of the Quick Access Toolbar and tick or untick the Minimize the Ribbon option.
This menu can also be accessed by right-clicking anywhere on the ribbon.
