I figured it out. I'll write this out in detail. Hopefully it will help future seekers.
As with other users on the forum, when the menu doesn't appear or actions don't compile correctly, you need to check for code exceptions or bad syntax in saved code. These errors can be anywhere in your code; they are not necessarily in the code you are having trouble with.
In my case, the Unity console window wasn't showing a compile exception. I had to hunt in Visual Studio for the exception there.
