Since the insertion point is in a table cell, the Quick Tag Selector shows the four tags leading up to that point.
One helpful coding tool you can use in Design view is the Quick Tag Selector. It's the row of buttons that appears at the top of the document window. When you select or click inside an element, it displays a button for that particular tag. It also gives you a quick representation of the parent and child tags that lead up to that element.
For example, in this illustration, the Quick Tag Selector shows the <body>, <table>, <tr>, and <td> buttons because the insertion point is within a table cell.
Note The Quick Tag Selector is on by default when you first install FrontPage. So unless you turned it off, it will be available for you.
