Where do the editing menus go?

In using the CS6 version of Adobe, and in editing a form - when I begin, I see all my TOOLS menu choices on the left.

But when I choose Forms Editing, the other tools disappear (specifically CONTENT), so I can't go back to edit objects without saving and closing the form and reopening.

Along the top of the form, the commands are disabled, so I can't get the tools back that way either.
