Choosing Options for Writer
Settings chosen on the pages in the OpenOffice Writer section of the Options dialog box determine how your Writer documents look and behave while you are working on them. If the Options dialog box is not already open, click Tools > Options.
Click the expansion symbol (+ sign or triangle) by OpenOffice Writer on the left-hand side of the Options—OpenOffice dialog box. A list of pages appears.
