URL Toggle in WebWorks Reverb
You can toggle between the Table of Contents or the Index in the Reverb output. For example, you can go to:
http://www.webworks.com/Documentation/Reverb/#toc/
http://www.webworks.com/Documentation/DITA_1.2_Specification/#index/
Clicking on those links brings up that part of the help by default as opposed to the regular view.
