title: How to submit a form on enter when the textarea has focus?
body: <p>When filling out a form's textarea, the default behavior when the enter key is hit is to move to the next line. How can I change the behavior of the form so it will submit upon user hitting enter even when the user is in a textarea? </p>
  
  <p>I used Firebug to checkout Stack&nbsp;Overflow's comment textarea (which has this behaviour), but couldn't see any JavaScript that achieved this affect. Is there a way to change the behavior of the textarea without using JavaScript?</p>
