			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)
	:wq		writes out changes to current file and quits
			the vi editor.

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.
