Interestingly, the Command Key+X, C or V ( for cut / copy / paste ) standard was introduced by Apple and later "adopted" by Microsoft, who substituted "Control" for "Command".
If you're used to the "MS way" as many see it, once you've found the Command key, copy and paste is exactly the same on Mac.
Typing this on my wife's MacBook Air, it is indeed a fine machine. Have fun.
