The key code outlet is not really ASCII. It is a platform-independent keyboard code that uses ASCII for letter keys and other values for things like function keys. The code is intended to be same on both Mac and Windows, at least where keys overlap. For example, if you type shift+B you will get the same thing out of the key code outlet as you will if you typed lower-case 'b' whereas the character code will be different.
Unfortunately, I didn't realize the nature of the new keyboard code until today when I started looking at this 'A' bug, but we will document what the codes are soon. It's possible the codes will change slightly on the Mac for non-US keyboards in the next update. We'll let you know.
