Material Tab

in New Users
How do I show the Material tab so that I can edit materials in Daz Studio 4.9. All the documentation makes it sound like it's easy. Should be easy. Haven't been able to find it, no matter how much I read the doc and search for it.

It's called the Surfaces tab. If you can't see it look under Windows/Tabs and it is at the bottom of the list.
Thank you!
