Hi,
I am using Emacs with X and struggling to do the following. How can I
preserve point's position while scrolling IN TEXT? I spent hours roaming
through Internet/searched the forum, but everyone seems to be interested in
preserving point's position on screen. I want to be able to use scroll bar
with a mouse or PageUp/Down to look something up and then return, but the
point insists on staying on screen.

I think that can't be done. If I remember correctly this was discussed
on Emacs devel a while ago.


I think one could write something like a modal scrolling,
like in this pseudo elisp.

(defun scroll-modal-pre-command-hook ()
  "Pseudocode!"
  (when (eq this-command 'scroll-bar-command)
    (save-window-excursion
      (while (scroll-bar-command-p)
        (apply 'scroll-command)
        (read-event)))))


I don't know if that's what eveybody has in mind here.
