Using VTEDIT with the HEATHKIT H19
                  ----------------------------------

     When VT edit is invoked, it transmits a code to put the H19
     in  its Alternate Keypad Mode.  The keypad now will perform
     the  special  function  operations  of  VTEDIT.   The  only
     disadvantage  is  that  the cursor control keys are also on
     the keypad.  To use them, the shift key must be  held  down
     too.  If you plan on doing a lot of manual cursor movement,
     you might want the keypad to remain in  the  shifted  mode.
     This  can  be  done  by taking the terminal off line BEFORE
     entering VT edit and typing  Escape  and  "x6".   Then  the
     cursor keys will respond without using the shift key.

     The H19 special function keys correspond to the PF keys  on
     a  VT100  as  described  in  the  VTEDIT  documentation  as
     follows:

             H19             VT100
            ------           -----
             BLUE             PF1        - 'GOLD' key
             RED              PF2
             GRAY             PF3
             f1               PF4

     Following is a diagram of the H19 keypad and the  functions
     associated with the various keys in different modes.

     'NORMAL'  is when the key is typed without typing the  BLUE
               key first.
     'GOLD'    is the action taken when the BLUE  key  is  typed
               immediately preceeding the keypad key.
     'SHIFTED' is the action taken when the shift  key  is  held
               down  while  the key is pressed ( assuming Keypad
               Shifted is disabled ).
