Changing Templates on the Fly

[armsys]

Now I understand how to decide which one, text or document, should be chosen for the template. Thanks a lot.
Nonetheless, the situation remiains unsatisfactory. Based on your guidance, I deem a list of files (ListPro files) should be assigned with the text template because I just want a list, no more and no less. It's text by nature, certainly not document. Once importing the said ListPro files by Ctrl+C, Ctrl+V (copy & paste), all Info Items are automatically assigned with the Document template. None can be changed back to the Text template. Now we go back to square one of the question--How to change the template from Document to Text?
