This typeface represents text as it appears on the screen.

Keyboard key names If you must press two or more keys simultaneously, the key names are 

linked with a plus sign (+), for example:

    Press Ctrl+Alt+Del 

The words “enter” 
and “type”

When you see the word “enter” in this guide, you must type 
something, and then press Return or Enter. Do not press Return or 
Enter when an instruction simply says “type.”

This typeface indicates the fixed part of a command text. You must type 
the command, or this part of the command, exactly as shown, and 
press Return or Enter when you are ready to enter the command.

Example: The command display history-command must be 
entered exactly as shown.

This typeface indicates the variable part of a command text. You must 
type a value here, and press Return or Enter when you are ready to 
enter the command.

Example: in the command super level , a value in the range 0 to 3 
must be entered in the position indicated by level 

{ x | y | ... }

Alternative items, one of which must be entered, are grouped in braces 
and separated by vertical bars. You must select and enter one of the 
items.

Example: in the command flow-control {hardware | none | 
software}

, the braces and the vertical bars combined indicate that 

you must enter one of the parameters. Enter either hardware, or 
none

, or software.
