Fading Multiple In And Out Divs On Click

What i would like to achieve is a single page with multiple fade in/fade out divs.
Like this section of the Apple site, click the navigation on the left, the different content sections fade in/out, the links are all hash links to id'd divs on the page. so the whole thing doesn't fall apart without the script.

I did a bit of a trawl and found this example that works on the mouseover, I had a look as the script and can't see how I would change it from 'hover' to 'click'.
The other I found was this one But the 'multiple' example on there seams to have some sort of 'flicker' and the examples all use script within the href which isn't great accessibility wise.

I also took a look at the Apple page, they are using 'scriptaculous' to do this, but they also do a bunch of other things on that page so finding the bit that just does the click fading, is a bit like a needle in a haystack.
