The eServices part of the Microsoft Office Web site has a bunch of different types of Smart Tags that you can download and add for use in Microsoft Office programs, such as Excel. These downloadable (and free) Smart Tags run the gamut from the Expedia Smart Tag — for getting travel-related information by entering destinations — all the way to the FedEx Smart Tag — for tracking your packages by its tracking number.

To get new Smart Tags for Excel, click the More Smart Tags button on the Smart Tags tab of the AutoCorrect dialog box (Tools, AutoCorrect). When you do this, Excel opens your Web browser, which then takes you to the Microsoft Office eServices home page, where you can follow links for getting Smart Tags in three major categories: Communication Services, Reference, and News & Travel.
