Smooth vertical page scrolling using mouse wheel and scroll bar

I am playing around and trying to build a parallax website - yes, I know they are an annoying fad but I would still like to have a go. So, for inspiration, I have been looking at various examples of good parallax websites and came across this one: https://victoriabeckham.landrover.com/INT. It has smooth scrolling using the mouse wheel, scrollbar, and anchor links. I have been searching for jQuery plugins that would achieve this effect but can only seem to find ones that use internal page links - anchor or ID's (detailed below) - but, not mouse wheel and scrollbar. There is a good chance that I am searching using the wrong keywords. Does anyone know the correct terminology to find these plugins or know any plugins that would achieve this effect? On a side note, I am currently learning jQuery and Javascript but am in the very early stages - still trawling through codeacademy and not made it onto any real world code yet. So at the moment I am playing with plugins as a way of learning but hopefully in a few months I can build my own stuff!
