Appendix A. The Windows keycodes

It's important to know the keycodes if you want to make more sophisticated listeners. If you wanted to distinguish between the left and right versions of the Shift , Control , and Alt keys you would need to be actively checking these keys in each call to your cController::update method. You might write a cControllerLeftRight child class with an overridden update to do this.

This is taken from the file winuser.h . The default set-up for keycodes is that for normal letters and numbers like 0 or Z, you don't use VK_0 and VK_Z, instead you use the traditional ASCII code symbols '0', 'Z', etc.
