title: Continuing the list with checkboxes
body: <p>Suppose that the cursor is currently after the word "bread" at the end of this piece:</p>
  
  <pre><code>* TODO Week1 [/]
  SCHEDULED: &lt;2015-08-09 Sun&gt;
  - [ ] Buy bread
  </code></pre>
  
  <p>When I press <code>Alt-Enter</code>, it adds a list item, but not a checkbox. Can I modify this behavior, so that a list that starts with a checkbox would continue with checkboxes as well?</p>
