I figured out a solution:
Copy the following code into the custom CSS section:
[code]
/* Back to Top Button */
a[href*="#top"] {font: bold 1.5em/34px "Lato",Arial,sans-serif;color: #FFF;margin: 0 0 0 44px;text-shadow: 0 1px 2px rgba(70,70,70,0.5);background: linear-gradient(0,#2182ac,#2aa3d8); padding:5px 15px 5px 15px; box-shadow: 0px 5px 10px #333; position:fixed; bottom:20px; right:20px;}
[/code]
For the page you want the button to appear on:
* Copy the page URL
* Go into page edit mode
* Create a new link with:
** Link_URL: (page url)'''#top''' <----- '' "Add #top to the end of the page url" ''
** Link_Text: '''back to top''' <------ '' "This text will appear on the button" ''
if done successfully the button will appear on the bottom right corner of the page.
