title: Emacs: multiple views of same file
body: <p>I'm trying to view the same file in 2 buffers, one at normal scale and the other zoomed out, to see the whole buffer (as in notepad++ document map: <a href="http://notepad-plus-plus.org/assets/images/docMap.png">http://notepad-plus-plus.org/assets/images/docMap.png</a> ).</p>
  
  <p>Is there any way visit the same file in different buffers, so that each buffer can have different settings?</p>
