  <p>I'm new to programming. What exactly is the "e" in function(e) in the code below? I'm guessing it's whatever the recipient of the method is, and what "this" refers to? Just a wild guess. But even so, wouldn't we be able to leave function(e) as function() without the "e"?</p>
  
  <pre><code>$("#" + id).live("mouseenter", function (e) {
      $(this).toggleClass("twittereyesopen");
  });
  </code></pre>
