You can use the numeric keypad on your terminal to enter PCA
    commands. When you press a defined keypad key, PCA accepts the
    associated "equivalence string" as command input. PCA predefines
    a number of keypad keys; pressing such a key enters the command.
    Some keys have GOLD definitions, and some have BLUE definitions.
    To access a GOLD definition, press the GOLD (PF1) key and then
    the defined keypad key. To access a BLUE definition, press the
    BLUE (PF4) key before pressing the defined keypad key. You can
    define your own keypad definitions with the DEFINE/KEY command.
