Copy Google Documents to Your Account !!!

Someone sent me the link to a document published using Google Docs, but I didn't have the permission to edit the document. I wanted to save the document to my Google Docs account, but none of the options offered by Google allowed me to do that.

One of the ways you could create a duplicate for the document is to replace

http://docs.google.com/View?docid=AAAAA

with

http://docs.google.com/DocAction?action=copy&docid=AAAAA

where AAAAA is the document ID. [.......]
