[TYPO3-english] Question about next/prev navigation

[Jeff Hollingsworth]

I am having trouble setting up the style of next/prev navigation I want 
for a section of a typo3 page tree.

I have a tree that looks like
	1.0	Topic 1
		1.1	Sub Topic A
		1.2	Sub Topic B
			1.2.1 Sub Sub Topic A
		1.3	Sub Topic C
	2.0	Topic 2

I would like the each of the pages to have a single next and prev button 
such that the next page is as follows:
	current page	page after pressing next
	1.0		1.1
	1.1		1.2
	1.2		1.2.1
	1.2.1		1.3
	1.3		2.0

In other words the next button does a depth first traversal of the page 
tree.

I have tried varitions on HMENU/TMENU plus the cag_pagebrowser 
extension.  With all of these methods, the next button navigates through 
the current level (and optionally produces links to descend levels). 
How can I get the single next button to work.?

Searching various typo3 resources has also failed me.

Sample TS or other help would be greatly appreciated.

Thanks,

Jeff Hollingsworth
