Custom help window can be opened by hacking into the Core.js file in MOSS 2007

I have been asked a few times about popping a custom help window (as opposed to a SharePoint Help window) while clicking on context sensitive help links on MOSS sites. This can be easily done by changing the "Core.js" file which can be found at "C:\Program Files\Common Files\Microsoft Shared\web server extensions\12\TEMPLATE\LAYOUTS\1033\Core.js" on your MOSS web server. Once you locate the file, find the Javascript function "HelpWindowHelper()" and change it to suite your requirements. An example is provided below:

function HelpWindowHelper(strParam)
{
var strHelpUrl;

if (typeof(strParam)=="undefined")
{strHelpUrl="/_layouts/help.aspx?Lcid="+L_Language_Text;}
else if (strParam == "&Key=Custom") /* Present new Custom Help Windows when parameter is 'Custom' */
{strHelpUrl="/pages/CustomHelp.aspx?Lcid="+L_Language_Text+strParam;}
else
{strHelpUrl="/_layouts/help.aspx?Lcid="+L_Language_Text+strParam;}
var wndHelp=window.open(strHelpUrl, "STSHELP",
"height=500,location=no,menubar=no,resizable=yes,scrollbars=yes,status=no,toolbar=no,width=475"
);
wndHelp.focus();
}

Please note that this change should be tracked and documented as its a unsupported hack for future Service Pack releases of MOSS 2007 (as SPs might overwrite "Core.js" with its own new version, in which case you will loose your changes if you havent documented them)
