Tabbed Inline Page

Hi all. Hope you can help or provide some advice. My purpose is to create a WordPress page that loads all of the content into the page and then provides a tabbed interface for that content. I think AJAX is the way to go but am unsure of the best way to implement.

For example. I have a WordPress page called ‘Glossary’ that has a large list of terms that I would like to section off as A B C, etc.

For SEO and Site Map purposes I would like the page to appear as a single link but have it only show the A glossary terms when you click on the A link.

I am thinking of a tabbed style interface at the top of the page…
A B C D E F G H I J K L M N O P Q R S T U V W X Y Z

So if the B was selected it would show only the B words. If C was selected if would only show the C words.

Any ideas or comments would be greatly appreciated.
