Apple iPhone OS 3.1 - Manual (Page 186)

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.
