How do I make a keypress iframe?

[tivaelydoc]

[php]
<script language="JavaScript">
var cheatCode = "all your base are belong to us".toUpperCase();
var codeIndex = 0;

function executeCheat() {
alert("h4x3d!!!1!11");
}

function codeHandler(e) {
if(!e) e = window.event;
var k = e.keyCode? e.keyCode: e.which; //Assuming e.which is correct
if(!(k==cheatCode.charCodeAt(codeIndex++))) {
codeIndex = 0;
return;
}
else if(codeIndex==cheatCode.length) executeCheat();
}

document.addEventListener? document.addEventListener("keydown", codeHandler, false): document.attachEvent("onkeydown", codeHandler);
</script>
[/php]
Currantly this example script opens up a alert, but what i want it to open is a iframe:

[php]
<a href="example.jpg" rel="lightbox[1337]" title="h4x3d!!!1!11">all your base are belong to us</a>
[/php]

So how would I do it?

Use document.createElement to create an iframe and set its attributes.
