This help topic describes the keypad definitions in the
    debugger's command interface. For information on keypad
    definitions in the graphical user interface (GUI), type HELP
    Keypad_Definitions_GUI.

    On Digital VT-series terminals and MicroVAX workstations, you
    can use the numeric keypad to enter debugger commands provided
    you are in "keypad mode." Keypad mode is enabled by default, but
    can be disabled and enabled by the SET MODE [NO]KEYPAD commands.
    In keypad mode, keypad keys are bound to commonly used debugger
    commands such as STEP, GO and EXAMINE. Most keys are bound to
    screen mode commands, to help you manipulate the predefined
    screen displays efficiently. Some keys are "terminated": the
    corresponding command is executed immediately. Others are
    not: you can enter additional parameters to the command before
    terminating it with a carriage return or the ENTER key. Also,
    some keys echo on the terminal while others do not, depending
    on the key. You can define your own keypad definitions with the
    DEFINE/KEY command.
