Hi, Melbert2000
It's not clear whether you already use RoboHelp or have installed the trial version as part of your evaluation. Assuming you have, each release of RoboHelp comes with sample projects to help explore features. For example, Adobe RoboHelp 8 comes with a project called Web Graphics.
One quick way to see the TOC/Index/Glossary in action would be on my site, called Clownfish School.

You will notice the Glossary is visible in two ways. First, as a Glossary button which shows in the Navigation pane. Second is in the form or expanding hotspots within topic text. You can see some examples if you go to the topic "News from Thailand and Greece" Click on the maroon color words "Anemonefish" and "Clownfish" and you will see how the Glossary hotspots show or hide as you click on them.
As part of your purchase evaluation, I would recommend you download the Adobe RoboHelp Reviewer's Guide here to get a better idea of the various features:

And the Web Graphics Sample project can be downloaded here:

Hope this helps.
