		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.
