How do I change the page layout from Portrait to Landscape for an entire document?

In your open document in OpenOffice.org:

1. Open the Styles and Formatting window [F11] (or choose Format > Styles and Formatting).
2. Click on the Page Styles icon (fourth icon from left).

If the list of page styles contains the selection Landscape, then select Landscape and proceed to create your document.

If the list of page styles does NOT contain the selection Landscape, then proceed as follows:

1. Default should already be highlighted. Right-click to see the context menu and select New.
2. In the dialog that appears, give the new page style a descriptive name, e.g. Landscape.
3. Click on the Page tab and change the page orientation to Landscape by clicking on the corresponding radio button. You may also make other changes to the page style, if needed (such as adjusting the margin sizes).
4. Click OK. The new style will appear as one of the page style choices.
5. Choose Landscape from the list of page styles.

The displayed page should now exhibit the new page style.
