The following is a list of the typographical conventions used in this book:
Used to indicate new terms, URLs, filenames, file extensions, and directories and to highlight comments in examples. For example, a path in the filesystem will appear as /Developer/Applications.
Used to show code examples, the contents of files, commands, or the output from commands.
Constant width bold
Used in examples and tables to show commands or other text that should be typed literally.
Used in examples and tables to show text that should be replaced with user-supplied values.
A carriage return ([RETURN]) at the end of a line of code is used to denote an unnatural line break; that is, you should not enter these as two lines of code, but as one continuous line. Multiple lines are used in these cases due to page width constraints.
When looking at the menus for any application, you will see some
symbols associated with keyboard shortcuts for a particular command.
For example, to open an old chat in iChat, you would go to the File
menu and select Open . . . (File 
Open . . . ), or you
could issue the keyboard shortcut, 
-O. The
symbol corresponds to the key (also known as the
"Command" key), located to the left
and right of the spacebar on any Macintosh keyboard.
