If you've been working with Office as you've worked through this and the earlier lessons of the book, you have probably seen smart tags as you followed along and learned the software. When you enter data in an Office program such as Word or PowerPoint, that Office program underlines the data with a purple dotted line indicating the smart tag. A smart tag is data that an Office product recognizes as data that fits within a category, such as one of these:
A person's name
A time (dates, times, even relative dates such as Last Friday)
Places
Recent Outlook recipients
