Boris RED Timeline Show/Hide Graph View?

I’m working with the latest Media100 on a MacPro5,1 with 64GB running High Sierra.

I accidentally hit the “Show/Hide Graph View” button in my Boris RED 5 timeline buttons. To my dismay, my familiar keyframes and tracks vanished. It took a bit of poking around to realize what happened. Things are back to normal now.

But now I want to know what the “Graph View” is used for? I couldn’t call up the local help files, they wouldn’t load properly in Firefox or Safari. I tried accessing the RED documentation on the BorisFx website but it wouldn’t load either, giving an error message about not being able to get a secure connection.

Can someone point me to where I might find more information, or explain what this feature is for? Thanks in advance. Jaeson
