User manual

For each bookmarked page, the screen lists the page number and either the
chapter number (if you bookmarked the first page of a chapter) or the first
line of text that appears on the page (if you bookmarked any page other
than the first page of a chapter).
To clear all the bookmarks, tap the Clear all button.
To clear an individual bookmark, tap the bookmark to visit its page, and
then tap the bookmark ribbon in the upper right corner.
Lookups
Tapping the Lookups tab displays the Lookups screen, which lists words
you have looked up while reading.
