Editing the AutoText. I followed your instructions: New mail from Home tab; Insert; click Quick Parts.

When I click on Quick Parts I see two blocks of my text. But I see no "edit text entry" when I right click. I can choose Edit Properties, but when I do I get the "Modify Building Block" box. I see no way to edit my text from this box.

I read the material after I clicked the question mark. These explanation did not shed light on my problem. It's not crucial but I wish I could find a solution to this puzzle.
