New to this

Hello, and welcome to my introduction/questions/Noobiness.  I'm NoMaD and VERY new to MSE. 

I just spent the last three days scanning through all the documentation I could find on the old and new forums, and have learned a lot. But I'm not a coder, and I'm getting to the age that it's hard to learn it, so there is a steep learning curve. 

Any help you guys could give me on the basics would be helpful.

Is there a tutorial on just shortcuts in MSE 2.0?

Oh, and one quick thing: I can't figure out how to add a watermark (one of many things I'm trying to learn) to my card. Is there a simple way to do it?

Thanks in advanced to everyone that can help me.
