All the features you are accustomed to using every day in Word are on the Ribbon, and much easier to find than ever before. But where are the behind-the-scenes settings that aren't about producing documents but that control how Word works? Settings like security and user information, spelling dictionaries and AutoCorrection?
In previous versions of Word, you clicked Options on the Tools menu. Now, all these settings are part of Word Options, which you open when you click the Word Options button on the menu that opens when you click the Microsoft Office Button.
