The » symbol leads you through nested menu items and dialog box options 
to a final action. The sequence File»Page Setup»Options directs you to 
pull down the File menu, select the Page Setup item, and select Options 
from the last dialog box.

Bold text denotes items that you must select or click in the software, such 
as menu items and dialog box options. Bold text also denotes parameter 
names.

Italic text denotes variables, emphasis, a cross-reference, or an introduction 
to a key concept. Italic text also denotes text that is a placeholder for a word 
or value that you must supply.
