VMS Help TCPIP Services, TELNET, Redefining TN3270 Keyboard, Key Definition File  *Conan The Librarian (sorry for the slow response - running on an old VAX)

    Use the DEFINE/KEY and DELETE/KEY statements to create your own
    key definition file as described in the following sections.

    The DEFINE/KEY statement assigns a new function to a particular
    key. Its format is:

    DEFINE/KEY [/STATE=EXTEND] key_name function

    /STATE         Optional. Default: non-extend mode.
                   Redefines the key in extend mode.
    key_name       Standard key name on the DIGITAL terminal.
    function       TN3270 function you want mapped to this key.

    You can define most of the named keys both in normal (non-extend)
    mode and in extend mode.

    You can define the control keys (and the synonyms for them) only
    in normal mode. Do not specify the qualifier /STATE=EXTEND.

    The following example assigns the EXIT function to the key
    sequence EXT + Z :

    DEFINE/KEY/STATE=EXTEND "Z" EXIT

    The DELETE/KEY statement removes the function assigned to a
    particular key. Its format is:

    DELETE/KEY [/STATE=EXTEND] key_name

    /STATE         Optional. Default: nonextend mode. Deletes the key
                   in extend mode.
    key_name       Standard key name on the DIGITAL terminal.
