Is it possible to set a custom mouse scroll distance?

I have seen plenty of sites out there (unfortunately I can’t think of any now) that move the page down 100% height when the user scrolls down. This is often used to reveal full height sections in a fairly “automated” way I guess. I hope this makes sense. I’ve been doing some research to figure out how it might be done without any success.

(Sorry, I don’t have a read-only link since the site I’m building isn’t too far along yet)

You may want to do a search for “Fullpage” as there are topics floating around regarding this.
