You might want to take the time to download the latest version from the
recent user contributions page.  It's much more feature rich with html
documentation.  The documentation still needs some work but that's
something I'll need to take up with David.

You will want to use onKeyDown instead of onKeyPress since onKeyDown will
return a scan code instead of a key code (which, as you noted, can change
depending on your OS language).  Scan codes will return the same value
regardless of what the key represents.  With a 'piano' type application,
you might also find onKeyUp to be rather useful (also returns a scan code).
