The e object holds a lot of information about the Netscape 6 event. The altKey property, for example, reveals whether the ALT key was in a pressed position during the event firing. The following statement prints true when the ALT key is pressed, and false otherwise:

window.status = e.altKey;
The status window is shown on the bottom left corner of Netscape 6 window. Notice that you have to pass the e object as a parameter to those functions which reference it. In the following example, we pass the e object as a parameter to colorItYellow() and colorItTan():

<DIV ID="demoDiv" STYLE="position:relative; left:100px; top:20px; width:120px; 
height:25px; color:blue; background-color:yellow;">Mouse over me!</DIV>
<SCRIPT LANGUAGE="JavaScript">
<!--
var demoObj;

function init() {
  demoObj = document.getElementById("demoDiv");
  demoObj.addEventListener("mouseover", colorItTan, false);
  demoObj.addEventListener("mouseout", colorItYellow, false);
}

function colorItTan(e) {
  demoObj.style.backgroundColor = "tan";
  window.status = e.altKey;
}

function colorItYellow(e) {
  demoObj.style.backgroundColor = "yellow";
  window.status = e.altKey;
}

onload = init; 
// -->
</SCRIPT>
Get on Netscape 6 browser and play with this demo.
