Have a look at http://www.pmwiki.org/wiki/PITS/00398

In particular:
When a visitor arrives on a page for the first time, all trails through that page should be "lit". When the visitor starts following a trail, other trails through the current page should "turn off". If the visitor leaves the trail for another page, such as by following an off-trail link, any trails through the new page should light up. So:
	• 	 proposed solution is that << PreviousPage | TrailPage | NextPage >> should generate [[PreviousPage(?trail=TrailPage)]] and [[NextPage(?trail=TrailPage)]] 
	• 	if I click previous or next, PmWiki now knows that I am moving along TrailPage's trail (from the ?trail=TrailPage in the address)
	• 	 so PmWiki can hide any other trails that may pass through the new page
	• 	 only trail links carry a ?trail= so following any other link will re-light the trails

 And this works whether the ?trail= a static wiki trail or a dynamic category trail.

Does this achieve what you want?
