The Microsoft Office Button appears in the upper-left corner of the window in several Microsoft Office programs. You get the same basic commands as appeared before on the File menu to open, save, and print your documents.

But the button offers more commands than the File menu did. For example, you've got support here for checking that files in Word, Excel, and PowerPoint don't contain private information or comments. You'll learn more about this in the practice steps at the end of the lesson.

The Microsoft Office Button also leads you to the program settings that control things like your preferences for correcting spelling.

Click Excel Options, Word Options, and so on, at the bottom of the menu, and then click any of the categories in the list on the left. For example, in Excel, click Formulas to turn the R1C1 reference style on or off. In Word, click Proofing to turn on or off the feature to check spelling as you type.

In previous versions of Office you could set options in the Options dialog box, which you opened through the Tools menu. Many of those options can now be found when you click the Microsoft Office Button — where they are more visible, and conveniently close at hand when you start work on old files or new ones.
