  36 ;;
  37 ;; To emulate the DEC LK-201 keypad keys on the PC 101 keyboard,
  38 ;; NumLock must be ON.
  39 ;;
  40 ;; The PC keypad keys are mapped to the corresponding DEC LK-201
  41 ;; keypad keys according to the corresponding physical position on
  42 ;; the keyboard.  Thus, the physical position of the PC keypad key
  43 ;; determines its function, not the PC keycap name.
  44 ;;
  45 ;; There are two LK-201 keypad keys needing special handling: PF1 and
  46 ;; the keypad comma key.
  47 ;;
  48 ;; PF1:
  49 ;;  Most PC software does not see a press of the NumLock key.  A TSR
  50 ;;  program distributed with MS-Kermit to support its VT-100 emulation
  51 ;;  solves this problem.  The TSR, called GOLD, causes a press of the
  52 ;;  keypad NumLock key to look as if the PC F1 key were pressed.  So
  53 ;;  the PC F1 key is mapped here to behave as the PF1 (GOLD) key.
  54 ;;  Then with GOLD loaded, the NumLock key will behave as the GOLD key.
  55 ;;
  56 ;;  By the way, with GOLD loaded, you can still toggle numlock on/off.
  57 ;;  GOLD binds this to Shift-NumLock.
  58 ;;
  59 ;; Keypad Comma:
  60 ;;  There is no physical PC keypad key to correspond to the LK-201
  61 ;;  keypad comma key.  So, the EDT Emulation is configured below to
  62 ;;  ignore attempts to bind functions to the keypad comma key.
  63 ;;
  64 ;; Finally, F2 through F12 are also available for making key bindings
  65 ;; in the EDT Emulation on the PC.  F1 is reserved for the GOLD key,
  66 ;; so don't attempt to bind anything to it.  Also, F13, F14, HELP, DO,
  67 ;; and F17 through F20 do not exist on the PC, so the EDT emulation is
  68 ;; configured below to ignore attempts to bind functions to those keys.
