Hey I stumbled upon a pretty awesome website covering every aspect of a 3d package like 3ds Max, Maya, Cinema4d, etc.

www.kxcad.net home

The downside on that website however is that you can't search anything.
I found a nice way to search what your looking for. Basically go to the sitemap of your desired package, hit ctrl+F and search.
Or just browse through it of course

Anyway hope this might help someone!

You can actually use google to search within most sites. Just type this into google:
site:http://www.kxcad.net/ search words

Ah, thanks for pointing that out ^^

It's just the same documentation that comes with these apps with ads slapped all over them...
