Get Item from list confusion

I think i have missed something simple here, please point me in the right direction. I would like to get each 2 indexes in the displayed in the list map node from vertex.point geometry node. should i be using keys or something like that? Many thanks!


Thank you very much Vikram.

Another way to do what you’re attempting, without sorting indices

I do not se that node List.Sort.ByKey…is it in some package?

I am on and Revit 2015…

It is available out of the box in


Edit: Sorry, it doesn’t work like List.SortByKey (which is available OOTB in the later versions)
