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.
