A concrete implementation of IKeyboardLayout based on keycodes.
The
keyCodeproperty of a'keydown'event is a browser and OS specific representation of the physical key (not character) which was pressed on a keyboard. While not the most convenient API, it is currently the only one which works reliably on all browsers.This class accepts a user-defined mapping of keycode to key, which allows for reliable shortcuts tailored to the user's system.
