I was looking for a smooth scroll to the top script so i found this very simple script which can be added as html code in the first section of your project. In the edit template part the script is as follows.

<script src="https://ajax.googleapis.com/ajax/libs/jquery/1.6.4/jquery.min.js" type="text/javascript"></script>
<style type="text/css">
#w2btoTop {display:none;text-decoration:none;position:fixed;bottom:10px;right:10px;overflow:hidden;width:51px;height:51px;border:none;text-indent:-999px;background:url(http://2.bp.blogspot.com/-oVa1ImctF7c/Tdouv3K7NyI/AAAAAAAAA38/xT4bu8uKM3M/way2blogging.org.ui.totop.png) no-repeat left top;}
#w2btoTopHover {background:url(http://2.bp.blogspot.com/-oVa1ImctF7c/Tdouv3K7NyI/AAAAAAAAA38/xT4bu8uKM3M/way2blogging.org.ui.totop.png) no-repeat left -51px;width:51px;height:51px;display:block;overflow:hidden;float:left;opacity: 0;-moz-opacity: 0;filter:alpha(opacity=0);}
#w2btoTop:active, #w2btoTop:focus {outline:none;}
</style>
<script src="http://bloggerblogwidgets.googlecode.com/files/w2b_jquery.ui.totop.js" type="text/javascript"></script>
<script type="text/javascript">
/*<![CDATA[*/
;(function($){$().UItoTop({easingType:'easeOutCirc'});})(jQuery);
/*]]>*/
</script>

I hope this helps others looking for the same problem.
