Does anyone know the greatest possible value the “keyCode” property will return?

I’m mostly worried about international keyboards.

I’m wanting to release a few KeyboardEvents myself using some rather nifty code (if I may say so myself) and want to make sure there are no future conflicts.

Each of my “special keys” have a unique id numbered sequentially. **Is there anywhere I can start my numbering from where I can be safe from conflicting key codes?** [/SIZE]
