How do I Open PRV in track view

[Leighton Cooper]

In Cake 8.5 it was possible to open prv in Track inspector but that feature seems gone.  Has the workflow in Cake Band changed quite a bit and how?  I'm trying to figure out the zooms and the microscope and they seem re-designed.   
Any ideas Thanks

I've got my main control bar (at the top) to show a module for several commands.  One of them is prv. I messed around in lenses and screensets until I got everything  the way I wanted , then saved it as a new lens. Most everything I use daily is one click away..            mark
