My reply is probably too late, as I don't check the forums that often.
- if you're looking for tabs, with or without a scrolling effect, then check out jquery tools download the tabs one, and/or with scrolling. You'll need jquery, which can be easily included using google's CDN.
- an alternative to the tabbed scrolling effect would be coda slider or jflow, which you can find a tutorial on here. both require jquery.
- if you want to scroll an entire page, as found on my site or here, get scrollTo
- There are of course other implementations using other libraries, such as moocontentscroller as mentioned above, which uses mootools
- here's another jquery scrolling effect
- you can also just google "content slider" for more stuff like this
good luck with whatever you're doing.
