when other javascripts are included in a webpage that use event handlers, eg prototype.js,
os_eventKeydown does not work (for example the arrow keys) because the keycode is undefined.

Replacing the line in os_eventKeydown

        os_cur_keypressed = (window.Event) ? e.which : e.keyCode;

with

        if (undefined != e.keyCode)       
            os_cur_keypressed = e.keyCode;
        else                              
            os_cur_keypressed = e.which;
