    On LK201 keyboards:

    o  You cannot define keys F1 to F5 or the arrow keys (E7 to E10).

    o  You can define keys F6 to F14 only if you have first entered
       the DCL command SET TERMINAL/NOLINE_EDITING. In that case, the
       line-editing functions of the left and right arrow keys (E8
       and E9) are disabled.

 equivalence-string

    Specifies the string to be processed when you press the specified
    key. Typically, this is one or more debugger commands. If the
    string includes any space or nonalphanumeric characters (for
    example, a semicolon separating two commands), enclose the string
    in quotation marks (").
