title: Space and enter "click" on the input that's focused. How do I disable this behavior?
body: <p>In chrome and firefox (and maybe others), if you've got an input focused, pressing "space" and "enter" clicks them for you.  I'm making an HTML 5 game and I want to rewrite how space and enter reacts on focus and the default behavior is getting in my way.  Is there a way to turn this default behavior off in most browsers?</p>
  
  <p><a href="http://jsfiddle.net/zmH5V/" rel="nofollow">Here's a jsfiddle</a> demonstrating the problem.  </p>
  
  <pre><code>&lt;button&gt;Button&lt;button&gt;
  $("button").on("click", function(event) { alert("Clicked"); });
  </code></pre>
  
  <p>If you click on the button, it displays the alert which is good.  But if you press "space" or "enter" after you click it, it also alerts.  I want to prevent this behavior so that I can write my own without them interfering.  </p>
