I posted yesterday the following to the Kobo developpers part of the forum.
Obviously, that was a wrong place considering the 0 answer I got.
I hope I have found the rigth team; if not would be kind enough to point me the rigth one

So, Hi guys.
I make ePub for my own on Kobo H2O.
I get problem with footnote.
I implement the call to footnote witk brakets to enlarge the reactive zone and save the actual notes in another file after the text.
All works fine in Calibre and does not go on Aura.

In fact, when I touch the screen shortly either nothing happen or the high or low menu is displayed ; when I do it longer it is a pop up menu which appears. When I hit screen on the boarder, the page is turned.
Does it exist some html tag to disable all those normal but borrowing actions ?
Thank you for the help.
