Many of the words you find in bold can also be found in the Index.
Italic font is used for chapter titles, section names, and titles of recom- mended reference works.
It may also be used when we want to empha- size a point. If you see something in italic font, pay attention . This includes much of what you might see on your screen, such as the names of files and folders, window titles, dialog box items, and menus. You may see bold Geneva used if we are referring to something important, such as a menu item you should remember. When we ask you to type some code on the keyboard, or show you a response that Perl provides, we'll use a fixed width font such as Courier .
