@psigu...

TL:DR; <https://en.wikipedia.org/wiki/Wikipedia:Too_long;_didn%27t_read> Is 
this your question:

>How can one loop through tiddlers which are two levels downstream in the 
tag-hierarchy or further?

If that is your question, I will attempt to reply. If you have some other 
*complex 
*question, I suggest you split it up into distinct questions, perhaps 
separate posts, so that they can more easily be dealt with.
