This is a bug in the page. In particular, showCode() has: var e = window.event || arguments.callee.caller.arguments; But am_fireEvent has this code in the !document.createEventObject branch: event = document.createEvent('HTMLEvents'); Note lack of |var|. So this is assigning the global "event" variable, which is the same thing as "window.event". After that, showCode always seems the event created by am_fireEvent as window.event, and that of course has no .which property. This "works correctly" in IE because IE itself will set window.event and also because the IE branch in am_fireEvent actually has |var event|.
