Onkeypress() [JavaScript]

vielleicht erstmal einbisschen Code

..
<head>
<Script for="bodyRightBottom_Doc" event="onKeypress()">')

var theAllCampaigns =new Array("...... ");

function crateTable(indexOfSelectedRow)
{
var BackColor;
var textColor;
...
document.writeln('</head>');
document.writeln('<body bgcolor="#D6D6D6">');
document.writeln('<table width="100%" border="0">')
for(var index=0;index<theAllCampaigns.length;index++){
if ((index & 1) == 0) {
BackColor = "#FFFFFF";
textColor="#000000";

} else {
BackColor = "E1F0FF";
textColor="#000000";
}
if(index== indexOfSelectedRow){
BackColor="#506EC8";
textColor="#FFFFFF";
}
//................

if(window.event.ctrlKey){
isCTRL_Press=true;
alert(isCTRL_Press);
}
//.........

document.writeln('<tr onClick="myAvtion()">');
document.writeln('bgcolor=' + BackColor + ' Style=color:' +
textColor + ' onDblClick="parent.addCampaignExpress(true,0)">');
document.writeln('<td width="10" bgColor="E1F0FF"> </td>');
document.writeln('<td width="65" align="left"> '+theAllCampaigns
[index] '</td>');
document.writeln('</tr>");
document.writeln('</table>");
...

Problem:

if(window.event.ctrlKey){
alert("Test Test");
}
lasst sich die tabelle nicht ausgenben
