Sticky tab menu that actually scrolls the page vertically?

Not sure if the title is clear enough but i'm looking for examples and thoughts on this type of components. I looked through some single page websites but couldn't find what I was looking for right away. What are your thoughts on tab-like menus usually on top of a page that actually vertically scrolls you to the relative section and are there any well executed examples that you can think of in a website? Thanks!
