As part of your Shared Borders, you probably indicated that you
wanted to include a Navigation Bar at the top, left, or both. You have a
lot of control over what links are displayed in these bars as well as
over their appearance. To get to the Navigation Bar properties, point at
the area of the shared border where the Bar exists and right-click.
Choose Navigation Bar Properties from the menu.
If you want to use pictures for the bar, rather than text links, you
should select a Theme first.
The other choice you have controls which pages are linked to in the
bar. This is based on the relationships found in the Navigation View.
For example, if you specify that "Child" pages will be in the
bar, then any pages below the current page in the hierarchy will be the
links displayed.
