New concepts or terms are generally in italic type when they first occur in text to indicate that they are defined in the paragraph.
Cross references within this manual usually include the title of the referenced section or chapter enclosed in quotation marks (e.g., see "Exploring on Your Own" on page 5-4).
Boldface type represents characters you enter as shown (literal expressions).
Lowercase italic type represents a variable, a placeholder for the text you actually enter. A variable can consist of different characters each time you make the entry.
Throughout this manual, you may be instructed to enter specific characters on the keyboard. These entry instructions (command lines) are printed in fixed-width boldface type (e.g., dothis) and appear either within a paragraph or on a separate line. Command lines are normally entered in lowercase.
San-serif boldface type (e.g., the Cancel button) represents boxes and buttons in dialog boxes, command names on pull-down menus, menu names, and hyperlinks.
Keys that are labeled on your keyboard with more than one character, such as the RETURN key, are identified by all uppercase letters in fixed-width font. Keys that you are to press simultaneously or in succession may be linked with a plus sign (e.g., press Ctrl+A) or a hyphen (e.g., press SHIFT-OPTION-d).
A selection from a menu may be presented with a colon separating the name of the menu and the specific item on the menu you should choose. For example, the notation Edit:Delete indicates that you should pull down the Edit menu and select Delete. In some cases, where a menu item opens another menu, a third level of information is shown. For example, Navigate:Hotlist Manager:Options means you should pull down the Navigate menu, choose the Hotlist Manager menu item, and then select the Options from that menu.
World Wide Web Uniform Resource Locators (URL) are shown in fixed-width font generally on a new line. URLs are case sensitive and must be entered exactly as shown.
