I opened Help from the Addess Book. When the Help Viewer opened, I searched for "directories." It returned "6 help topics, 6 support articles." I double-clicked on one of the support articles, and it opened one of the Knowledge Base articles in the Help Viewer window.
I think it's great that they're integrating the Knowledge Base and local Help!
