title: Selecting the first "n" items with jQuery
body: <p>With Jquery, I need to select just the first "n" items from the page, for example the first 20  links instead of selecting all of them with the usual</p>
  
  <pre><code>$("a")
  </code></pre>
  
  <p>Sounds simple but the jQuery manual has no evidence of something like this.</p>
