[Orgmode] org-info.js : How to put link on "go back to last / forward to next visited section." ?

[Xin Shi]

Hello Experts,

On the exported html page with org-info.js, one can go to the next page by clicking the "Next" or simply type "n" as indicated in the help menu by typing "?". An example page is:

http://orgmode.org/Changes.html

If one jumps randomly in the page, one can also go back to the last visited section by typing "b". It is very handy in a long documentation. However, for viewer with only clickable input (such as mouse), it's quite easy to get lost. So, I'm wondering if it's possible (or easy) to put a link either on the top or bottom of the page? The layout might looks like this:

Previous | Next  | Back | Forward     .....                  Version 6.33                      1

Thanks!
Xin
