        !            10: ;; Here's my EDT emulation for GNU Emacs that is based on the EDT emulation
        !            11: ;; for Gosling's Emacs sent out on the net a couple of years ago by Lynn Olson
        !            12: ;; at Tektronics.  This emulation was widely distributed as the file edt.ml
        !            13: ;; in the maclib directory of most Emacs distributions.
        !            14: ;;      
        !            15: ;; My emulation consists of two files: edt.el and edtdoc.el.  The edtdoc.el file
        !            16: ;; is the documentation, that you can add to the beginning of edt.el if you
        !            17: ;; want.  I have split them because I have been loading the edt.el file a lot
        !            18: ;; during debugging.
        !            19: ;;      
        !            20: ;; I will gladly take all criticisms and complaints to heart, and will fix
        !            21: ;; what bugs I can find.   As this is my first elisp hack, you may have to
        !            22: ;; root out a few nasties hidden in the code.  Please let me know if you
        !            23: ;; find any (sorry,
        !            24: ;; no rewards :-).  I would also be interested if there are better,
        !            25: ;; cleaner, faster ways of doing some of the things that I have done.
        !            26: ;;      
        !            27: ;; You must understand some design considerations that I had in mind.
        !            28: ;; The intention was not really to "emulate" EDT, but rather to take advantage
        !            29: ;; of the years of EDT experience that had accumulated in my right hand,
        !            30: ;; while at the same time taking advantage of EMACS.
        !            31: ;;      
        !            32: ;; Some major differences are:
        !            33: ;;      
        !            34: ;; HELP            is describe-key;
        !            35: ;; GOLD/HELP       is describe-function;
        !            36: ;; FIND            is isearch-forward/backward;
        !            37: ;; GOLD/HELP       is occur-menu, which finds all occurrences of a search string;
        !            38: ;; ENTER           is other-window;
        !            39: ;; SUBS            is subprocess-command.  Note that you will have to change this
        !            40: ;;                 yourself to shell if you are running Un*x;
        !            41: ;; PAGE            is next-paragraph, because that's more useful than page.
        !            42: ;; SPECINS         is copy-to-killring;
        !            43: ;; GOLD/GOLD       is mark-section-wisely, which is my command to mark the
        !            44: ;;                 section in a manner consistent with the major-mode.  It
        !            45: ;;                 uses mark-defun for emacs-lisp, lisp, mark-c-function for C,
        !            46: ;;                 and mark-paragraph for other modes.
        !            47: ;;      
        !            48: ;;      
        !            49: ;; Some subtle differences are:
        !            50: ;;      
        !            51: ;; APPEND          is append-to-buffer.  One doesn't append to the kill ring much
        !            52: ;;                 and SPECINS is now copy-to-killring;
        !            53: ;; REPLACE         is replace-regexp;
        !            54: ;; FILL            is fill-region-wisely, which uses indent-region for C, lisp
        !            55: ;;                 emacs-lisp, and fill-region for others. It asks if you really
        !            56: ;;                 want to fill-region in TeX-mode, because I find this to be
        !            57: ;;                 very dangerous.
        !            58: ;; CHNGCASE        is case-flip for the character under the cursor only.
        !            59: ;;                 I felt that case-flip region is unlikely, as usually you
        !            60: ;;                 upcase-region or downcase region.  Also, unlike EDT it
        !            61: ;;                 is independent of the direction you are going, as that
        !            62: ;;                 drives me nuts.
        !            63: ;;      
        !            64: ;; I use Emacs definition of what a word is.  This is considerably different from
        !            65: ;; what EDT thinks a word is.  This is not good for dyed-in-the-wool EDT fans,
        !            66: ;; but is probably preferable for experienced Emacs users.  My assumption is that
        !            67: ;; the former are a dying breed now that GNU Emacs has made it to VMS, but let me
        !            68: ;; know how you feel.  Also, when you undelete a word it leave the point at the
        !            69: ;; end of the undeleted text, rather than the beginning.  I might change this
        !            70: ;; as I'm not sure if I like this or not. I'm also not sure if I want it to
        !            71: ;; set the mark each time you delete a character or word.
        !            72: ;;      
        !            73: ;; Backspace does not invoke beginning-of-line, because ^H is the help prefix,
        !            74: ;; and I felt it should be left as such.  You can change this if you like.
        !            75: ;;      
        !            76: ;; The ADVANCE and BACKUP keys do not work as terminators for forward or
        !            77: ;; backward searches. In Emacs, all search strings are terminated by return.
        !            78: ;; The searches will however go forward or backward depending on your current
        !            79: ;; direction.  Also, when you change directions, the mode line will not be
        !            80: ;; updated immediately, but only when you next execute an emacs function.
        !            81: ;; Personally, I consider this to be a bug, not a feature.
        !            82: ;;      
        !            83: ;; This should also work with VT-2xx's, though I haven't tested it extensively
        !            84: ;; on those terminals.  It assumes that the CSI-map of vt_200.el has been defined.
        !            85: ;;      
        !            86: ;; There are also a whole bunch of GOLD letter, and GOLD character bindings:
