Writer has three ways to view and edit a document: Normal, Web, and Full Screen. To change the view, go to the View menu and click the required view.

You can also choose View > Zoom > Zoom on the Menu bar to display the Zoom & View Layout dialog, where you can set the same options as on the Status bar.

You can also use File > Print Preview, or press Ctrl+Shift+O, to view the document, but this view does not allow editing. 

Normal view is the default view in Writer.
