you lost me.  absolute_url() in a method will render the URL to the
folder that contains the method.  absolute_url in a document will render
the absolute url of the document.

yes.

There is a list of objects from you to the root folder called PARENTS. 
'You' are PARENTS[0], your parent is PARENTS[1], your grandparent is
PARENTS[2], and the root folder is PARENTS[-1] (the last element in the
list).

<a href="<dtml-var "PARENTS[-1].absolute_url()">">This link goes to the
root folder.</a>

Also, there is URLx.  URL is your URL.  URL1 is the URL of your parent. 
URL2 is the URL of your grandparent and so on.

<a href="<dtml-var URL1>">Click to go up one parent.</a>
