## Documentation conventions

Following are all the special characters and typographical conventions used in this manual:

#### Convention | #### Meaning
--- | ---
`Monospace text` | Represents text that appears on your computer's screen, or that could appear on your computer's screen.
Boldface mono-space text | Represents characters that you enter exactly as shown (unless the characters are also in italics-see Italics, below). If you could enter the characters but are not specifically instructed to, they do not appear in boldface.
Italics | Represent variable information. Do not enter the words themselves in the command. Enter the information they represent. In ordinary text, italics are used for titles of publications, for some terms that would otherwise be in quotation marks, and to show emphasis.
[ ] | Square brackets indicate an optional argument you might add to a command. To include such an argument, type only the information inside the brackets. Do not type the brackets unless they appear in bold type.

> | Points to the next level in the path to a parameter or menu item. The item that follows the angle bracket is one of the options that appears when you select the item that precedes the angle bracket.
Key1-Key2 | Represents a combination keystroke. To enter a combination keystroke, press the first key and hold it down while you press one or more other keys. Release all the keys at the same time. (For example, Ctrl-H means hold down the Control key and press the H key.)
Press Enter | Means press the Enter, or Return, key or its equivalent on your computer.
Note: | Introduces important additional information.
Caution: | Warns that a failure to follow the recommended procedure could result in loss of data or damage to equipment.
