The rotor control is an invisible dial that you can use to change the  
results of up and down flick gestures when VoiceOver is turned on.
Operate a rotor:

Rotate two fingers on the iPhone screen to “turn” the dial to choose  
between options.

The effect of the rotor depends on what you’re doing. For example, if  
you’re reading text in an email you received, you can use the rotor to  
switch between hearing text spoken word-by-word or character-by- 
character when you flick up or down. If you’re browsing a webpage, use  
the rotor to choose whether you hear text word-by-word or character-by- 
character, hear just the headers, hear just the links (all of them,  
visited links, or links not yet visited), hear form elements, or hear  
descriptions of images. In other words, you can use the rotor setting  
to hear all the text, or to jump from one element to another of a  
certain type, such as headers or links.

Rotor options depend on the context of what you’re doing.
