Related navigation tutorial?

Hello-

I’m hoping someone can point me in the right direction in how I would go about scripting a simple navigation that is similar to the one found here:

I’m not asking for specific code, but I know there has to be a tutorial/source out there that relates to the same simple style, and I just can’t find it. I’m a beginner to actionscript, but I do know the basics. Any and all suggestions are appreciated, thanks in advance!
