title: How can I block comment code in the IPython notebook?
body: <p>I have defined a function in an IPython notebook and would like to be able to block comment a section of it.  Intuitively, I'd expect to be able to highlight a section of code, right click and have an option to comment out the selection but this has not been implemented.  </p>
  
  <p>Is there a way to do this? </p>
