[sacrificial first line for hungry relay sites]
This file eases the pain for VMS users making the transition onto
a UNIX system, provided that the system has the James Gosling's CMU Emacs
installed. This .emacs_pro file combines the keypad characteristics of the
DEC EDT editor with the flexibility of the Emacs editor. The keypad
controls windows, cut-and-pastes, cursor motion, deletes, undeletes, and
a multistep UNDO function. It does require a VT-100 or similar ANSI X3.64
terminal to generate appropriate escape sequences from the keypad.
The file replaces the default .emacs_pro file with the material below.
;This .emacs_pro file maps the keypad of a VT-Series terminal into a command
;set resembling the DEC EDT (tm) editor. Most of the unshifted functions are
;unaltered - removing only three EDT functions, PAGE, CHAR, and ENTER. These
;are redefined into Paragraph, Window, and Newline-and-Indent.
;BackSpace is used in the usual UNIX (tm) fashion to delete previous
;characters, leaving the Delete key to serve as the Beginning-of-Line. This is
;the reverse of the DEC EDT editor, true, but is preferable to having different
;delete keys in and out of Emacs. LineFeed is used for the EDT function of
;delete-previous-word.
;
;The shifted GOLD/Keys are mostly unaltered, with SPECINS replaced
;by ^\, UND W and UND C replaced by UND LWC. SUBS and RESET are eliminated.
;All of these keys are redefined as:
;
;SPECINS -> : Copy Mark/Dot Region
;UND W -> : Split Window
;UND C -> : Visit Buffer
;SUBS -> : Visit File
;RESET -> : Exchange Mark/Dot
;
; New commands are GOLD/GOLD, which turns on the new-undo function.
;Other new commands are GOLD/keyboard pairs, which are mapped as follows:
;
;GOLD/up-arrow : Current line to top of window.
;GOLD/down-arrow: Current line to bottom of window.
;GOLD/left-arrow: Backward sentence.
;GOLD/right-arrow: Forward sentence.
;GOLD/- : Goto percentage of buffer.
;GOLD/= : Goto line number.
;GOLD/` : Display line number and character number.
;GOLD/p : Delete selected buffer.
;GOLD/[ : Delete Mark/Dot region to selected buffer.
;GOLD/] : Paste selected buffer at dot.
;GOLD/BackSpace : Delete other windows.
;GOLD/Delete : List Buffers.
;GOLD/ \ : Capitalize word.
;GOLD/LineFeed : Delete-next-word. (Deletes fragments, unlike Del W).
;
; The following commands alter the Emacs default key map. Aside from
;these changes, all other Emacs commands retain the documented bindings.
;
; Delete : Beginning-of-Line.
; LineFeed : Delete-Previous-Word.
; ^A : Enlarge current window.
; ^Q : Reserved for X-ON flow control.
; ^S : Reserved for X-OFF flow control.
; ^Z : Extended-Command, with prompts for different exits.
; ^_ : Pause-Emacs. (Type "fg" to restore paused Emacs.)
;
