The ZNavigator product was designed to simplify the construction of navigation bars. It was written to make navbar management easy for inexperienced contents managers, and provide some nifty features. Many of the features and their usage are demonstrated in the navigator_demo package, which you can import with the name 'navigator_demo.zexp' from the Zope management interface.
