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”
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.”
