    DEFINE_KEY Function: RECORD

    Saves a keystroke sequence on a specific PF key. Invoke the
    RECORD function with the appropriate key sequence, press the
    PF key as prompted, enter the keystroke sequence, and then invoke
    the RECORD function again. You can save a maximum number of 127
    keystrokes on each PF key. If the status display is enabled when
    you use the RECORD function, the letter R appears on the status
    line.

    To recall the keystroke sequence, use the PLAY function. To
    cancel the RECORD function, use the DV CNCL function. To erase
    all previously recorded key sequences, use the ER INP function.
