Shading/UV's Tab on the Tool Shelf?

I’m working through a tutorial that refers to the Shading/UV’s tab on the Tool Shelf. Since I don’t see that tab on either 2.78 or 2.79, I referred to the Blender 2.79 Manual. Unfortunately, that didn’t help. On the first page of the manual’s Interface>Windows System>Tabs and Panels section, near the top right is a screen shot of the tool shelf that shows the Shading/UV’s tab. However, below it on the same page is another screen shot that shows it absent. It shows the same tabs I see on both 2.78 and 2.79: Tools, Create, Relations, Animation, Physics, and Grease Pencil.

Am I nuts or what?

Thanks, Richard. I guess I am nuts after all. :o
