RIght that is correct.

We don't have many options. We only have two stylee: One used for the
tracker and another one to use the tracker data to navigate around.

Sure, What you can do is look at the TrackerStyle class. You can very
easily add a new style class that can respond to mouse clicks or anything
else. The current style won't work in your configuration because it needs
tracker and 3 buttons for navigation.

That would be great. I am willing to help you if you are willing to share
the code and add a new class to ParaView. Please let me know.
