I assume you mean the last set:

Code:
<!--(EOF - 2.1) Responsive DIY Template Default for 1.5.x (65)-->

<script src="<?php echo $template->get_template_dir('jquery.tabSlideOut.v1.3.js',DIR_WS_TEMPLATE, $current_page_base,'jscript') . '/jquery.tabSlideOut.v1.3.js' ?>" type="text/javascript"></script>

    <script type="text/javascript">
    $(function(){
        $('.slide-out-div').tabSlideOut({
            tabHandle: '.handle',                     //class of the element that will become your tab
            pathToTabImage: '<?php echo $template->get_template_dir('tab.png',DIR_WS_TEMPLATE, $current_page_base,'images') . '/tab.png' ?>', //path to the image for the tab //Optionally can be set using css
            imageHeight: '50px',                     //height of tab image           //Optionally can be set using css
            imageWidth: '60px',                       //width of tab image            //Optionally can be set using css
	    tabLocation: 'left',                      //side of screen where tab lives, top, right, bottom, or left
            speed: 300,                               //speed of animation
            action: 'click',                          //options: 'click' or 'hover', action to trigger animation
            topPos: '100px',                          //position from the top/ use if tabLocation is left or right
            leftPos: '20px',                          //position from left/ use if tabLocation is bottom or top
            fixedPosition: true                      //options: true makes it stick(fixed position) on scroll
        });

    });

    </script>

   <div class="slide-out-div">
    <a class="handle" href="http://link-for-non-js-users.html">Content</a>
<?php echo SLIDE_OUT_CONTENT; ?>
         </div>
since it refers to slide out. Correct?
