Command: listxdef
  LISTXDEF lists all current XKeyb key allocations to STDOUT.
Syntax:
  listxdef
Options:
  - none -
Comments:
  LISTXDEF is used to output (to STDOUT) the definition file currently
  being used by XKEYB (including any keys defined using KEYMAN).
  It is most commonly used to save a custom definition file (ie. one
  created by loading one of the standard definition files with XKEYB
  then assigning additional macros using KEYMAN).
  This is done using the command:
    KEYMAN >xyz.KEY
  Please see the manual XKEYB.TXT for further information.
