Where can I learn the advanced mechanics of SSB4?

[Maruken]

So, I've been searching everywhere for the usage of advanced mechanics so that I can move on from mashing buttons. What I mean by this is, is there a link that I can go to to learn how to mix up? How to dodge punish? How to OOS whatever that is? I'm just not aware of these advanced mechanics in SSB4 and I've been wanting to learn these for ages. Is there a list of these so I can learn each one individually?

The first place I can think of off the top of my head:

Then click Ctrl + F, then paste this into the little bar that appears:
Advanced Character Options and Basic Combinations of Options


Also, Oos means "Out of Shield".
