To The Top Link

This script will provide a link to the top of the page as means to get back to the main navigation. In other words, this allows users to go back the main navigation from almost every scrolling position. It may also be convenient for disabled users who scrolling is difficult to do.

Login to your Dashboard> Layout> Edit Html. Next, copy the script source code below and paste between the closing b:skin tag and the closing head tag.
<script src='http://javascripthost.com/s1/bin/jumptop.js'/>
That's all for now. Save the template and you're done!
