I'm trying to figure out how to bind a key combination to a function which
would move the cursor forward about 80 characters (or back 80 characters).
I sometimes type very long lines in emacs and would like to be able to
navigate through the line quicker than one space at a time or one word at
a time. Thanks for any advice anyone can provide!

The fastest way to accomplish this is to use incremental search (either
C-s or C-r). Find a word  or substring you want to move to and then press
C-s to move forward or C-r to move backward. Hold down Ctl key and keep
pressing s or r until you get to the instance of the substring you want
and then press Return. The cursor will then be positioned after the
substring. I would bet a not inconsequential sum of money that this will
turn out to me (much!) faster than hardwiring a "forward80" function to a
keychord.

Ed,

That is excellent! I tried it out and decided I won't bet against you. I can use C-s and C-r to zip around my document pretty quick that way. Never thought to use "search" for navigation.

Pete, I edit text files on my home OS X machine over SSH while I'm traveling (often visiting family). I like to use Terminal because I don't need any software installed on whoever's machine I'm using.

Is ``C-u 8 0 C-f'' too long for you?  You do it with a function if you
really wanted to..

Such a function, btw, could look like this:

(global-set-key "\C-cf" '(lambda ()
                            (interactive)
                            (forward-char 80)))

Well, that's great! The built-in key combination is almost good enough, but I think I might need to do the custom key binding so that I can rapidly jump the cursor 80 characters, repeatedly. If I have a line that takes up 10 lines on the screen (a paragraph of text, for instance), and I need to get to the center of that paragraph, I'd have to jump forward several times to get there. (I think the key binding would be easier for me than trying to guess exactly how many characters to jump forward.)

Does anyone know an easier way to cursor around a very long line? I'm pretty frustrated with how I can't simply hit the up arrow and move up to the previous line on the screen (which is actually part of the same very long line), but it's an improvement over PICO which always adds a carriage return at the edge of the screen. I use the Terminal program in Mac OS X which doesn't seem to allow mouse input.

Thanks a lot for your help! Merry Christmas!

You can install a 'Carbon Emacs' of any flavour, or compile an 
experimental version with a Cocoa (Aqua-tic) interface. All run as 
tools/windows in Mac OS X and you can use the mouse. One of them (at 
least) is even on Apple's download page of free or not so free UNIX 
utilities.

You should try longlines-mode. In this mode returns inserted by the 
user are "hard" returns. The returns inserted by the filling 
functions, which prevent the lines from running off the screen, are 
"soft" returns. Soft returns are automatically removed when the text 
is saved to disk. You can navigate through single long line 
displayed in several lines as through many short lines, by hitting 
up/down arrow or C-p, C-n (like in PICO). To use this mode you need 
longlines.el file. If you use EmacsFromCVS you already have it. In 
other case you can download it from http://cvs.savannah.gnu.org/
viewcvs/emacs/emacs/lisp/longlines.el
Add something like this to your ~/.emacs:
(require 'longlines)
(global-set-key "\C-c\C-q" 'longlines-mode)
(global-set-key "\C-cq" 'refill-mode)
Then open a file and hit C-c C-q and C-c q to turn on both modes. 
Hit M-q at a long line to break it with "soft" returns. You can 
write a function to automatically break all lines (search at 
emacswiki.org)

I'm not positive, but it sounds like this might do what you
want.

Put this into your init file, ~/.emacs.el or whatever. (This
works on either Emacs or XEmacs, but the init file would be
named differently.)  You can change the name of the function
from "fld-jmp80" to anything you happen to like, but it is wise
to pick a prefix that will never be used by any other module,
just to avoid stepping on something else.  Typicall the
programer's initials or a prefix specifying the name of the
module are used.

This function can take an optional argument, but the default
argument is 1.  With the (default) argument of 1 it will move
the cursor forward by 80 characters.  With any other argument it
will move the cursor backwards by 80 characters..

(defun fld-jmp80 (&optional fld-arg)
  "Move cursor forward or backward 80 characters.
   The default argument is 1, which moves characters forward,
   any other argument will move 80 characters backwards."
  (interactive "p")
  (let ((fld-cnt))
    (setq fld-cnt -80)
    (if (eq 1 fld-arg) (setq fld-cnt 80))
    (forward-char fld-cnt)))

You will also want to bind this to a key sequence, such as
a function key.

Here are ways to bind this function to various keys.  Choose a
key sequency you like, and using one of these as an example,
put a command into your init file to bind your function to
your choise of keys.

  (global-set-key        "\C-a"      'fld-jmp80)  ;; Cntl-A
  (global-set-key        "\C-x\C-a"  'fld-jmp80)  ;; Cntl-X Cntl-A
  (define-key ctl-x-map  "\C-a"      'fld-jmp80)  ;; Cntl-X Cntl-A
  (define-key esc-map    "a"         'fld-jmp80)  ;; Esc A
  (global-set-key [(insert)]         'fld-jmp80)  ;; "Insert" fkey
  (define-key global-map  [f5]       'fld-jmp80)  ;; F5 fkey

``C-8 0 C-f'' is even faster for me -- I know it runs forward-char 80
times instead of just once, but for reasonable values of 80 I prefer
computer to work harder if it saves me the extra keystroke :)
