The following typographical conventions are used in this book:

Italic

Used for new terms where they are defined, URLs, filenames, file extensions, directories, commands, and options. For example, a path in the filesystem will appear in the text as C:\Windows.

Constant width

Used for HTML tags and to show the contents of files and the output from commands.

Constant width bold

Used for emphasis in code examples and for text that should be typed literally by the user.

Menus/navigation

Menus and their options are presented in the text as File Open, Edit Copy, and so on. Arrows are also used to signify navigation paths when using window options; for example, Control Panel Add/Remove Programs Internet Explorer Remove means that you should launch the Control Panel, click the icon for Add/Remove Programs, select Internet Explorer, and then click Remove (if only Microsoft really made it that easy!).

Pathnames

Pathnames are used to show the location of a file or application in the filesystem. Folders are separated by backward slashes. For example, if you're told to "launch the Firefox application (C:\Program Files\Mozilla Firefox)," that means you can find the Firefox application in the Mozilla subfolder of the Program Files folder.
