You can use smart tags (smart tags: Data recognized and labeled as a particular type. For example, a person's name or the name of a recent Microsoft Outlook e-mail message recipient is a type of data that can be recognized and labeled with a smart tag.) to perform actions in Microsoft Excel that you'd usually open other programs to perform. For example, if you type a U.S. financial symbol such as MSFT in a cell, the Smart Tag Actions button provides a list of smart tag actions you can perform. The purple triangle in the corner of a worksheet cell indicates smart tags.
