I've read through all the help guides in Word 2013 for Quick Parts and AutoText but I still can't do the simple job of editing the AutoText that I have on the Quick Access Toolbar.

Of course I followed your suggestion but this just transferred the edited text to Quick Parts. When I am in Quick Parts I can place the mouse pointer over AutoText. Then I see the text I want to change. But I don't know how to make the change. I can't transfer the change I made in Quick Parts to the AutoText.

It should be so simple to edit my paragraph! It's frustrating not to be able to do it.
