        :w      write out current changes.  The vi editor works
                on a copy of your file.  The :w command causes
                the editor to write its copy over the original
                which is on the disk.
        :w name write out changes to the file  name  .  This is
                like the :w command but the changes are written
                into the file you specify.  (good for making
                intermediate copies)
Cut and Paste   Move to the begining of the text to cut.  Use
                dd to delete (cut) several lines.  Use D to cut
                only the end of one line.  Move to the place
                where you wish to paste the text.  Use P to 
                put back the text. You may need to clean up
                the spacing after pasting.
