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