[HOW-TO] Display pager in the top of the node in Drupal 6 with Zen Theme

I need to display pager for both top and bottom of the node for user to easily to move between pages. The one in the bottom is normally display but I want it to display in the top section also. To do that, Just put the following code :

<?php echo theme('pager', null, 1, 0, array(), 9); ?>

If you want to change the number of pages in the list, just change number 9 to anything you want.

When put that code in page.tpl.php, it will look like below :

.
.
.
        <?php if ($breadcrumb || $title || $tabs || $help || $messages): ?>
          <div id="content-header">
            <?php print $breadcrumb; ?>
            <?php if ($title): ?>
              <h1 class="title"><?php print $title; ?></h1>
            <?php endif; ?>
            <?php print $messages; ?>
            <?php if ($tabs): ?>
              <div class="tabs"><?php print $tabs; ?></div>
            <?php endif; ?>
            <?php print $help; ?>
          </div> <!-- /#content-header -->
        <?php endif; ?>
        <?php echo theme('pager', null, 1, 0, array(), 9); ?>
        <div id="content-area">
          <?php print $content; ?>
        </div>

        <?php if ($feed_icons): ?>
          <div class="feed-icons"><?php print $feed_icons; ?></div>
        <?php endif; ?>
.
