GET_INFO(KEY_MAP)

     For an overview of the GET_INFO built-in, see the HELP topic GET_INFO.

     When parameter1 is KEY_MAP, GET_INFO takes a third parameter.  The
     parameter is a string that is the name of the key map list containing
     the key map you want.

     The following strings can be used for parameter2 when parameter1 is the
     keyword KEY_MAP:

       Parameter 2       | Return Value (Parameter 1 is keyword KEY_MAP)
      -------------------+------------------------------------------------+
       "first"           | String   -  First key map in the key-map list
                         | 0        -  if no key maps found
       "last"            | String   -  Last key map in the key-map list
                         | 0        -  if no key maps found
       "next"            | String   -  Next key map in the key-map list
                         | 0        -  if no key maps found
       "previous"        | String   -  Previous key map in the key-map list
                         | 0        -  if no key maps found

      Use string constant "first", before using "next". Use "last" before
      using "previous".
