35 ;; Associate EDT keynames with Emacs terminal function vector names.
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.
