I do not have access to the Chinese version of the game, as far as I know. Though, other than the main window class name, I am unsure how it would be much different, as I have not seen a Chinese keyboard or in-game skillbar.
If someone can send me the main window class info, and the default keys which are equivalent to '1' and '2' on US101/102 keyboards, then I can make the requested changes. I would prefer the Virtual-Key Code for the keys used to fire the Catapult/Trebuchet, and the two Flame Ram skills.
