Control/Alt/Soft Detection in AS2.

In Actionscript, you can detect Alt/Control/■■■■ + Whatever other key you press like this:
AS3:
stage.addEventListener(KeyboardEvent.KEY_DOWN, displayKey);

function displayKey(keyEvent:KeyboardEvent)
{

var modifier:String = "";

if (keyEvent.ctrlKey)
{

	modifier = "Ctrl + ";

}
else if (keyEvent.altKey)
{
	modifier = "Alt + ";
}
else if (keyEvent.shiftKey)
{

	modifier = "Shift + ";
}

yText.text = modifier + keyEvent.keyCode;

}

In AS2 you can do this:
var keyListener:Object = new Object();

keyListener.onKeyDown = function()
{
yText.text = Key.getCode();
}
Key.addListener(keyListener);
But this AS2 code only allow single detection of keys, does AS2 support detecting of control/Alt/Shift + other keys like AS3 ?
