In most .tpl's you'll find:
Code:
{ include file="location.tpl" last_location="Last Location" }
Which sets the last element of the location variable.
This is in home.php which sets the first part of the location:
Code:
if(!empty($current_category)) $location = $category_location;
You can also find more in include/categories.php:
Code:
$category_location[]=array(ereg_replace(".*/","",$val),"home.php?cat=".$categoryid);
hth.
