| > ## Typographic and Keying Conventions This guide uses the following typographic conventions:
Bold | Bold words or characters represent system elements that you must use literally, such as commands, options, and pathnames.
Italic | Italic words or characters represent variable values that you must supply.
Constant width | Examples and information that the system displays appear in constant width typeface.
[ ] | Brackets enclose optional items in format and syntax descriptions.
{ } | Braces enclose a list from which you must choose an item in format and syntax descriptions.
| | A vertical bar separates items in a list of choices.
< > | Angle brackets enclose the name of a key on the keyboard.
... | Horizontal ellipsis points indicate that you can repeat the preceding item one or more times.
This guide uses the following keying conventions:
<Ctrl-x> or ^x | The notation <Ctrl -x > or ^x followed by the name of a key indicates a control character sequence. For example, <Ctrl-C> means that you hold down the control key while pressing <C>.
<Return> | The notation <Return> refers to the key on your terminal or workstation that is labeled with the word Return or Enter, or with a left arrow.
