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