Learning Mac OS X takes some time ...

Having been a Windows and KDE / Linux user for many years I have found learning the shortcuts on a Mac OS X (Aqua) quite frustrating, however, once I have learned them I believe they are way more powerful than the Windows / KDE variants. I think this has a bit to do with the fact that Mac OS X uses different names for the term I am used to in the other OSs.

What I need is a good place to learn all of these commands :-)
