title: Jump to next code cell (IPython notebook)
body: <p>I use the IPython 2.0 Notebook for teaching.</p>
  
  <p>The notebooks are created before the teaching session, and used as-is during the session.</p>
  
  <p>Sure, when I <em>prepare</em> the notebook, it has sense that I access all the cells in sequence (actually, I don't).</p>
  
  <p>Back in class, while I present the concepts and the code to the students, I don't need the focus to be put on the next cell, I just need the cursor to wait in the next <em>code</em> cell...</p>
  
  <p>The best I can hope is that someone has been able to change the default behaviour of Shift-Enter, so that it executes the current cell, and jump to the next <em>executable</em> cell.</p>
  
  <p>Has it been done?</p>
