Documentation for Motion Modifiers

[Lightbringer]

I was exploring the motion modifiers, and I found one that was potentially useful for my project. I opened up the help to see what it did, but I could not find any documentation for it. Upon closer inspection, I found many of the newer modifiers are not documented. I thought perhaps my documentation was out of date, so I downloaded the latest PDFs right off the main Lightwave download page, but they also had the same omissions as the Web-based help I see from 10.1.

Is there more up-to-date documentation somewhere?
