Creating 'Next' and 'Prev' links

[mikewafer]

Hi,

I have created a nav based on the anchor method you listed here: https://github.com/pixxelfactory/jInvertScroll/issues/2

In addition to the main nav, I wish to have a pair of Prev and Next buttons (which I will fix left and right) that toggle through the anchors. This has me stumped. Any help would be appreciated. Working site Dev is here: http://tinyurl.com/p3cl2lt

Grazie!
