This feature allows you to place bookmarks throughout the program. Just like regular bookmarks, they let you quickly go back to a position you've saved earlier.
When you get to a place you'd like to come back to later, choose Set Bookmark from the Tool menu. This displays a box with ten slots for bookmarks. Just select one of the boxes to store your bookmark. When you choose Browse Bookmarks, also in the Tool menu, you get the same screen, but any bookmarks you've set will have little pictures of the screen in the boxes. If you select a set bookmark, it will take you to that screen.
You can also set bookmarks using the keyboard. The numbers one through zero on the keyboard correspond to the bookmarks one through ten. Simply press a number and that screen will be stored in that bookmark. Be careful though, if a bookmark already exists in the slot you've chosen, it will be overwritten with the new entry. This is true both from the keyboard and using the mouse.
