title: Vim and python - jump to definition key binding
body: <p>The <a href="http://www.youtube.com/watch?v=YhqsjUUHj6g&amp;t=27m57s" rel="noreferrer">following youtube video</a> shows that it is possible to jump to definition using vim for python.</p>
  
  <p>However when I try the same shortcut (Ctrl-G) it doesnt work...
  How is it possible to perform the same "jump to definition"?</p>
  
  <p>I installed the plugin Ctrl-P but not rope.</p>
