I'm impressed that the emulators are able to pass the keystrokes to the parent OS... are they also running WoW on the emulator or is KeyClone somehow able to capture those windows even though they are on the mac? (Like is MacOS enumerating the processes to the windows emulation?)
These emulators usually aren't emulators. They are usually an implementation of the Windows API for a different Operating System. Wine (for Linux) does that too. It implements the Windows API and also puts the hardware into some kind of abstraction layer.
In this case, keyboard and mouse input would go over such an abstraction layer so the Windows and non-Windows programs can interact (e.g. stuff like copy pasting could work)
