Scrolling Navigation

This page demonstrates a basic scrolling navigation I wrote. When you scroll or when you click on the arrows, it shows the up and down arrows as needed and tracks where you are. On the first pane, the up arrow does not show. On the last pane, the bottom arrow does not show. Both arrows show in the panes between the first and last. View the source and look for the comment "START CODE TO COPY and remember to include a jQuery call." Also, get additional artifacts here.
