title: How to close the doc reading part of the IPython notebook?
body: <p>In an IPython notebook, when you look at some docs with <code>?</code> or <code>help()</code>, a split frame is opened at the bottom of the screen where the documentation shows up.
  While I find this useful as a guide for continuing to play with some Python code, I would like to close this spit frame when I'm done reading the docs, so to get back the screen space.
  But I can't find instructions anywhere, not with Google and not in the IPython notebook docs how to do this?</p>
  
  <p>Anybody knows?</p>
