Did you know that the Thumbnails, Bookmarks, Annotations, Signatures, Destinations and
Article Tabs can be made to float?
Simply show the Navigation Pane (Show/Hide Navigation Button on the Toolbar), then Click
and Drag a Tab (grab the Title) out into the Document Window (see Figure 1.1).
To put them back, grab the Title of the tab (not the Window) and drag it back into the
Navigation Pane window.
