Adobe Acrobat 7 Professional - Manual (Page 101)

Using the pages pane of the Organizer window
The pages pane of the Organizer window displays thumbnails for every page of all PDF files that are selected in the files
pane. The Zoom slider and buttons at the bottom of the pages pane let you adjust the size of the page thumbnails. If a
selected PDF file contains special document properties, such as layers, attachments, or a digital signature, an icon
appears for each property in the thumbnail's title bar; placing the pointer over the icon displays a tool tip identifying
those properties.
