Writer has several ways to view a document: Print Layout, Web Layout, and Full Screen. To access these and other choices, go to the View menu and click on the required view. (When in Full Screen view, press the Esc key to return to either Print or Web Layout view.)
When in Web Layout, you can use the Zoom slider on the Status bar, as described above. In Print Layout, you can use both the Zoom slider and the View Layout icons on the Status bar.
You can also choose View > Zoom from the menu bar to display the Zoom & View Layout dialog, where you can set the same options as on the Status bar. In Web Layout view, most of the choices are not available.
