@Guessed: I already thought about it but with automation, i.e. making a loop on the doc to run the code I did with regex for each slice of 100 pages. But the thing is that I'm beginner with VBA Word and it's hard to deal with range and selection (does anybody know a good introduction to this kind of basis? ). So, what happens is that the indexes I get are from the beginning of the selection (e.g. from page 200 to page 300), but the footnotes are placed as if the selection started at the beginning of my doc !

But I keep thinking about it, and if someone can answer one of the initial question I asked, that is how index (in regex object) represents exactly, and how it works, it would be very pleasant for me. Indeed, I am not far from what I am looking for, so I'd like to understand what is wrong. And then I will be able to concentrate on the Find approach...

Thanks .
