;; ====================================================================

;; 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.

Tip: Filter by directory path e.g. /media app.js to search for public/media/app.js.
Tip: Use camelCasing e.g. ProjME to search for ProjectModifiedEvent.java.
Tip: Filter by extension type e.g. /repo .js to search for all .js files in the /repo directory.
Tip: Separate your search with spaces e.g. /ssh pom.xml to search for src/ssh/pom.xml.
Tip: Use ↑ and ↓ arrow keys to navigate and return to view the file.
Tip: You can also navigate files with Ctrl+j (next) and Ctrl+k (previous) and view the file with Ctrl+o.
Tip: You can also navigate files with Alt+j (next) and Alt+k (previous) and view the file with Alt+o.
