Dear there,
I have data file with many columns. The first line has field names as usual.
I am reading column 35 for example, CTRL+v will turn the page BUT focus on
column 1, and I have to locate column 35 again -:) Is there a convenient
way?
Also is it possible to keep the first line (table field names) visible while
browse line 200?
Thanks for your reply in advance.
Michael

Indeed.
,----[ C-h f set-goal-column RET ]
| set-goal-column is an interactive compiled Lisp function in `simple.el'.
| It is bound to C-x C-n.
| (set-goal-column ARG)
|
| Set the current horizontal position as a goal for C-n and C-p.
| Those commands will move to this position in the line moved to
| rather than trying to keep the same horizontal position.
| With a non-nil argument, clears out the goal column
| so that C-n and C-p resume vertical motion.
| The goal column is stored in the variable `goal-column'.

You need to eval this the buffers context (e.g. with M-:).

thanks, Andreas, it works pretty well. is it possible to out the code in
.emacs, or even bind it to a key?
(setq header-line-format
(buffer-substring 1 (line-end-position (goto-char 1))))
so I don't need to type it in everytime. After all, it is a common task for
me to read tables.
Sincerely Yours,
Michael

Try this function, you can bind it like any other command.
(defun buffer-line-as-header (&optional lnum)
"Use line at linenumber LNUM as headerline, defaulting to the current line.
With a non-numeric prefix arg (C-g), restore the default value of
`header-line-format'. Otherwise the prefix arg determines the linenumber to
use."
(interactive "P")
(let ((lnum (if (null lnum)
(line-number-at-pos)
(if (numberp lnum)
lnum
0))))
(cond
((or (< lnum 0)
(> lnum (line-number-at-pos (point-max))))
(error "No such linenumber : %d" lnum))
((= 0 lnum)
(setq header-line-format (default-value 'header-line-format)))
(t
(save-excursion
(goto-line lnum)
(setq header-line-format
`(:eval (let ((line ,(buffer-substring (line-beginning-position) (line-end-position))))
(concat ;;acount for fringes, scroll-bar and scrolling
(propertize " " 'display (list 'space :width
(+ (fringe-columns 'left t)
(scroll-bar-columns 'left))))
(substring line (min (1- (length line))
