The keyboard shortcut for copying a layer and pasting it in CS6 is Ctrl+C.
I understand you're trying to duplicate a layer without copying it into another group. I searched for alternatives, but nothing matches what you're looking for. The site you found suggested using Ctrl+Shift+C, which doesn't work for you. You're frustrated because your current software restricts this action.
