inventory filtering macro (work in progress)

first draft:
/goto '?'':(function(){
	var ftextboop = $$ ;
	top.mainpane.location = 'inventory.php';
	document.mainpane.text.value = ftextboop ;
})();
z='

current draft (leaves loading inventory.php to an auxiliary macro [probably '/goto inventory.php?ftext=___' with the 3 undercores being literal and not a placeholder] and will probably need to end up becoming an onload script in inventory.php's header somehow) :
/goto '?'':(function(){ top.mainpane.frameElement.contentDocument.forms[2].children[0].value += '$$' ; throw{}})();z='
