title: Pycharm: Hotkey to go to the file window
body: <p>How can I go back to my file edition when I am in a tool window (Console, Project, ...) in pycharm.</p>
  
  <p>I see shortcut for the tool windows (CMD+1, CMD+4, ...), but I cannot go back to my file edition without closing the actual tool window and without the mouse.</p>
  
  <p>Is there a hotkey that exists to do that?</p>
