[NTG-context] Absolute positioning

Hello, I didn't find a way to put text at specific locations on the page. It must be something obvious! :-) I try to design a screen document where every notes are, say, typeset on the lower half of the page and appear only when clicking on their number in the text (with layers I think). Thnaks in advance, Gilles. PS for Hans: I didn't forget the note problem we've discussed in Mâcon. I'll build a test file.
