5-way controller— selects an item or action when pressed down. Moves the
on-screen highlight or cursor up and down when moved up and down. Moves the
on-screen highlight or cursor side-to-side when moved left or right. Holding the 5-way
controller up or down without releasing it accelerates the cursor movement, making it
faster to navigate through lists or text.

browser. For example, you can follow a link in a book and then press the Back button
to return to your place.
Keyboard— use to enter search terms, notes in your content, URLs for websites, etc.
Symbol key — presents a menu of punctuation marks and symbols. Move the
5-way controller to select the desired symbol and press the 5-way to select.
Text key — adjusts font size and number of words per line to suit your reading
preference. Also allows you to turn on/off Text-to-Speech, zoom into PDF documents,
and to change the screen rotation settings.
