Hello.Sorry, Jan, but I have no idea what you mean. Did you tell me if you think there is something like CUA on OSX? Or do you think someone not familiar with OSX can look that up in a few minutes? (I am sure I can't.)
Are you annoying on purpose, or are you pulling my leg?
Well, in the world outside, there is this thing called internet. You can search it for various information, one such place is Google. There you can type in (for example) "osx default key shortcuts". Then you find pages like this (first hit):
Scroll down to Application and other OS X shortcuts, near the middle.
Jeez...
