title: Search in PyCharm interactive console command history
body: <p>PyCharm keeps a command history for it's interactive Python console.</p>
  
  <p>Is there a way to access this history with some sort of search instead of just browsing the entries with the arrow keys in the interactive console window?</p>
  
  <p>My environment: PyCharm 2.7 EAP (124.138) on MacOS X 10.8.2.</p>
