The script generator runs on the script, hotkey.js. Here is an updated version:

Code:
var thecode=''

function step1(){
document.final1.final2.value='Generating code...please stand by'
setTimeout("step2()",1000)
}

function step2(){
document.final1.final2.value='<script language="JavaScript1.2">\n\n'
document.final1.final2.value+='\/*\nHome Hot Key Script- \nŠ Dynamic Drive (www.dynamicdrive.com)\nFor full source code, installation instructions,\n100\'s more DHTML scripts, and Terms Of\nUse, visit dynamicdrive.com\n*\/\n\n'
document.final1.final2.value+='var hotkey='+thecode+'\nvar destination="http://www.dynamicdrive.com"\nif (document.layers)\ndocument.captureEvents(Event.KEYPRESS)\nfunction backhome(e){\nif (document.layers){\nif (e.which==hotkey)\nwindow.location=destination\n}\nelse if (document.all){\nif (event.keyCode==hotkey)\nwindow.location=destination\n}\nelse if((!document.all)&&(document.getElementById)){\nif (e==hotkey)\nwindow.location=destination\n}\n}\ndocument.onkeypress=backhome\n\n<\/script>'
}


function generatecode(){
if (document.key1.key2.value.length==1){
if ((document.layers)||((!document.all)&&(document.getElementById)))
thecode=document.key1.key2.value.charCodeAt(0)
step1()
}
else
alert("Please enter only one key!")
}

function generatecode2(){
if (document.all)
thecode=event.keyCode
event.cancelBubble=true

}
if (document.all)
document.key1.key2.onkeypress=generatecode2
And on the page where this generator is run advise the users to insert this event handler in their body tag:

HTML Code:
<body onkeypress="if ((document.getElementById)&&(!document.all)){backhome(event.which)}">
