I'm looking at the manual for Vertex Groups Panel Controls, here. It's for version 2.78, and I'm running 2.78 (image pasting is not working on stackexchange for me at the moment, so I will paste my screenshots and provide URLs).

The manual states that I should see "Assign" and "Weight" controls in the Vertex Groups box when a certain group is made active (light blue). Here's a screenshot from the manual:

But I don't see this on my screen. I have made the vertex group active, but I don't see the "Assign" and "Weight."

I'm stuck with no way to hook my armature bones up to my vertices. Please help!
I also have not been able to find the controls for "weight painting." Alt, Shift, Ctrl, etc., in all combinations with W didn't surface weight painting for me.
