;; Here's my EDT emulation for GNU Emacs that is based on the EDT emulation
;; for Gosling's Emacs sent out on the net a couple of years ago by Lynn Olson
;; at Tektronics. This emulation was widely distributed as the file edt.ml
;; in the maclib directory of most Emacs distributions.
;; My emulation consists of two files: edt.el and edtdoc.el. The edtdoc.el file
;; is the documentation, that you can add to the beginning of edt.el if you
;; want. I have split them because I have been loading the edt.el file a lot
;; I will gladly take all criticisms and complaints to heart, and will fix
;; what bugs I can find. As this is my first elisp hack, you may have to
;; root out a few nasties hidden in the code. Please let me know if you
;; no rewards :-). I would also be interested if there are better,
;; cleaner, faster ways of doing some of the things that I have done.
;; You must understand some design considerations that I had in mind.
;; The intention was not really to "emulate" EDT, but rather to take advantage
;; of the years of EDT experience that had accumulated in my right hand,
;; while at the same time taking advantage of EMACS.
;; Some major differences are:
;; GOLD/HELP is describe-function;
;; FIND is isearch-forward/backward;
;; GOLD/HELP is occur-menu, which finds all occurrences of a search string;
;; ENTER is other-window;
;; SUBS is subprocess-command. Note that you will have to change this
;; yourself to shell if you are running Un*x;
;; PAGE is next-paragraph, because that's more useful than page.
;; SPECINS is copy-to-killring;
;; GOLD/GOLD is mark-section-wisely, which is my command to mark the
;; section in a manner consistent with the major-mode. It
;; uses mark-defun for emacs-lisp, lisp, mark-c-function for C,
;; and mark-paragraph for other modes.
;; Some subtle differences are:
;; APPEND is append-to-buffer. One doesn't append to the kill ring much
;; and SPECINS is now copy-to-killring;
;; REPLACE is replace-regexp;
;; FILL is fill-region-wisely, which uses indent-region for C, lisp
;; emacs-lisp, and fill-region for others. It asks if you really
;; want to fill-region in TeX-mode, because I find this to be
;; CHNGCASE is case-flip for the character under the cursor only.
;; I felt that case-flip region is unlikely, as usually you
;; upcase-region or downcase region. Also, unlike EDT it
;; is independent of the direction you are going, as that
;; I use Emacs definition of what a word is. This is considerably different from
;; what EDT thinks a word is. This is not good for dyed-in-the-wool EDT fans,
;; but is probably preferable for experienced Emacs users. My assumption is that
;; the former are a dying breed now that GNU Emacs has made it to VMS, but let me
;; know how you feel. Also, when you undelete a word it leave the point at the
;; end of the undeleted text, rather than the beginning. I might change this
;; as I'm not sure if I like this or not. I'm also not sure if I want it to
;; set the mark each time you delete a character or word.
;; Backspace does not invoke beginning-of-line, because ^H is the help prefix,
;; and I felt it should be left as such. You can change this if you like.
;; The ADVANCE and BACKUP keys do not work as terminators for forward or
;; backward searches. In Emacs, all search strings are terminated by return.
;; The searches will however go forward or backward depending on your current
;; direction. Also, when you change directions, the mode line will not be
;; updated immediately, but only when you next execute an emacs function.
;; Personally, I consider this to be a bug, not a feature.
;; This should also work with VT-2xx's, though I haven't tested it extensively
;; on those terminals. It assumes that the CSI-map of vt_200.el has been defined.
;; There are also a whole bunch of GOLD letter, and GOLD character bindings:
;; look at edtdoc.el for them, or better still, look at the edt.el lisp code,
;; because after all, in the true Lisp tradition, the source code is *assumed*
;; to be self-documenting :-)
