The altkey and ctrlKey are set to undefined state in the event object used in the onchange event handler

below is the example code:
<script language="javascript" type="text/javascript">

function ev_handler(ev) {

    alert("  altKey pressed: "  + ev.altKey + 
            " ctrlKey pressed: " + ev.ctrlkey);
    return;
}

</script>

<select onchange="javascript: ev_handler(event)">
<option value='1'>one
<option value='2'>two
<option value='3'>three
</select>

Reproducible: Always

Steps to Reproduce:
1. run the above code
2. change select option with alt or ctrl key pressed
3. alert message shows key press as undefined 
Actual Results:  
shows keypress during an onchange event is undefined

Expected Results:  
should have return a bool value of the key press (even in onchange event)

this works with IE7

change event is not a mouse event, nor key event, so altKey and ctrlKey aren't
defined. That is per W3C DOM Events spec. So this is INVALID unless we want to
support these IE's extensions.

Thanks, Smaug. Marking as INVALID. (We can cover supporting IE's extensions in another bug, if there isn't one filed already.)
