	enter the command exactly as shown and then
	press Return or Enter. Commands appear in bold.

	This guide always gives the full form of a
	command in uppercase and lowercase letters.
	However, you can abbreviate commands by
	entering the fewest letters in each command that
	identify a unique command. Commands are not
	case sensitive.
The words “enter”	When you see the word “enter” in this guide,
and “type”	you must type something, and then press Return
	or Enter. Do not press Return or Enter when an
	instruction simply says “type.”
Keyboard key	If you must press two or more keys
names	simultaneously, the key names are linked with a
	plus sign (+). Example:
		Press Ctrl+Alt+Del
Words in italics	Italics are used to:
	■	Emphasize a point.
	■	Denote a new term at the place where it is
		defined in the text.
