Forum:Links to "top" of page

I am trying to find out how to put a link in the middle of my page to direct readers back to the top of the page.

Also, I'd like to add a list at the top of the major headings found in that page that a user can click and be directed to that section of the page. Can anyone help? I have not seen any instructions on how to link to spots within the same page. Thanks to anyone with added expertise!
