$[officename] uses page styles to specify the orientation of the pages in a document. Page styles define more page properties, as for example header and footer or page margins. You can either change the “Default” page style for the current document, or you can define own page styles and apply those page styles to any parts of your text. To change the page orientation of one or more pages in a document from portrait to landscape in a document, you must first create a page style that uses the landscape orientation, and then apply the page style to the pages.
