Besides not being able to use the help file, what questions do you have?
I don't think I've ever used a help file except to see if there was any information in it that I could point to helping out here.
Just open it up and use it. Try out stuff. Experiment with Smart Groups. Poke around and little and see what happens.
If a card doesn't have the fields you are looking for, go to the Card menu and Add Field. Besides Groups (and Smart Groups) there isn't much to it.
As you found out, the option key provides some options. However, Contacts being very basic, doesn't have much beyond what you found.
