Just before the Menu button is the Previous button, which is used to move backward one navigation point to the previous point as selected with the Menu button. If BARD Mobile is in stop mode, each time the Previous button is activated, the book narrator will read the heading of the new item selected. If it is in play mode, playback will start from the new location.
Pressing the Previous button for an extended time will move navigation toward the beginning of the book in increments of five navigation elements. TalkBack users can double tap and hold the button to accomplish the same results.
