   navigation actions this isn't needed. E.g. popular operation
   systems switch tabs on `mousedown`.

   You can also apply `[up-follow]` to any element that contains a link
   in order to enlarge the link's click area:
 

  current `<body>` element with the response's `<body>` element

      <a href="/users" up-follow>User list</a>
  
  By also adding an `up-instant` attribute, the page will be fetched
  on `mousedown` instead of `click`, making the interaction even faster:
  

  Follows this link via AJAX and replaces a CSS selector in the current page
  with corresponding elements from a new page fetched from the server:

      <a href="/posts/5" up-target=".main">Read post</a>

  \#\#\#\# Updating multiple fragments

  You can update multiple fragments from a single request by separating
  separators with a comma (like in CSS). E.g. if opening a post should
  also update a bubble showing the number of unread posts, you might
  do this:

      <a href="/posts/5" up-target=".main, .unread-count">Read post</a>

  \#\#\#\# Appending or prepending instead of replacing

  By default Up.js will replace the given selector with the same
  selector from a freshly fetched page. Instead of replacing you
  can *append* the loaded content to the existing content by using the
  `:after` pseudo selector. In the same fashion, you can use `:before`
  to indicate that you would like the *prepend* the loaded content.

  A practical example would be a paginated list of items. Below the list is
  a button to load the next page. You can append to the existing list
  by using `:after` in the `up-target` selector like this:

      <ul class="tasks">
        <li>Wash car</li>
        <li>Purchase supplies</li>
        <li>Fix tent</li>
      </ul>

      <a href="/page/2" class="next-page" up-target=".tasks:after, .next-page">
        Load more tasks
      </a>

  By also adding an `up-instant` attribute, the page will be fetched
