Normal vu qu'il s'agit d'un concept qui etend l'usage habituel de ces touches, mais le brevet specifie bien que c'est un comportement different du Page Up / Page Down habituel :
However, pressing the Page Down or Page Up keyboard buttons to navigate content provides sometimes unexpected results for many viewers. More particularly, unless the zoom percentage setting and/or size of the window is coincidentally set such that an entire page is shown at once, pressing the Page Down or Page up key does not move the content a full page. Such behavior is the default experience in applications.
Bref, il faut vraiment avoir les yeux derriere la tete pour melanger les 2.
