David,


My experience with TalkBack is like your experience with Voiceover. 
Users simply swipe vertically or horizontally to find out if there's 
more info. some apps have tabs across the top or bottom of the screen 
(e.g., the phone app has Speed Dial, Call History, and Contacts). Users 
can either swipe horizontally with two fingers one or more times or tap 
one of the tabs.


Once in a very long while, I come across an app that has a scroll icon. 
Mostly it's been confusing because the swipe works and because the 
scroll icon doesn't do so consistently. Of course, I can't think of any 
examples right now.


Hope this helps.


Ciao
