I was okay when I had the proper keyboard in front of me, but I still stumble with reflexively using the correct keys for shortcuts when I'm remote controlling one from the other. I've found it very difficult to use Ctrl+C to copy from Windows and then Cmd+V to paste on Mac OS without pretty frequently using the wrong modifier key.
