Pull down just a little, tap the page navigation, scroll, scroll, scroll to whatever page. That's a terrible way to page jump. Not only is that bad all by itself, but pull just a little too much and now you aren't navigating pages, you are refreshing. I've never seen pulling down activate two different functions.
Besides that, the whole selection within bb10 menus is terrible with one selection per screen-wide choice. Ugly and not intuitive.
