Your new control center, the Ribbon, in Word 2007.
Yes, there's a lot of change to familiar Microsoft Office programs. But the good news is that the commands and other tools you need are now exposed and more readily available.
Instead of having 30 or so undisplayed toolbars, and commands buried on menus or in dialog boxes, you now have one control center that brings the essentials together and makes them very visual.
And once you learn how to use the Ribbon in one program, you'll find it easy to use in other programs too.
