edit text inside a flowchart shape

I've a flowchart and text inside objects. 

For love or money I cannot figure out how to edit the text inside the shape. None of the various options (\edit text, Ctr-Sh-T, etc) work.  I cannot ungroup the  object to select only the text.

How can I do that?

    • Try selecting the text inside the Object Manager Docker.

      • No, that doesn't seem to do it.

        But after a frustrating few minutes trying clicking everything I found that it seems simply using the text tool allows one to edit the text.

        Odd as I thought I had tried that but I guess not.   However the other usual things - double clicking on the text, etc etc does not activate the text tool - it seems that it has to be specifically chosen.
