I can't seem to find a way to rename a sentence diagram. Is there and if so how?
Never fails. As soon as I post a question here I find the answer.
You have to select the Text tool in the diagram window on the upper left and then click on the title. I was not choosing the text tool.
BTW this is not at all intuitive. It would be nice if the Arrow tool would also make the title change to an editable box.
