Q999 How can I avoid using opener.opener every time when referring to many variables in the window that opened the window that opened the current window?

You can make a reference to the openers opener, and then use that each time:

<script language="JavaScript"><!--
var myTop = opener.opener;

alert(myTop.variableName);
//--></script>
