scroll without moving the point

scroll without moving the point

[Olive]

Hello,

Is there a way to configure emacs in order that when I scroll (usually 
with the mouse wheel), the point (the cursor position) stay at the same 
position in the buffer, even if this point is not in the visible part 
anymore? this could be usefull to see a matching parenthesis or the 
beginning of a region, etc...

   Is there a way to configure emacs in order that when I scroll (usually 
   with the mouse wheel), the point (the cursor position) stay at the same 
   position in the buffer, even if this point is not in the visible part 
   anymore? this could be usefull to see a matching parenthesis or the 
   beginning of a region, etc...

For finding a matching parenthesis, I'd recommend using `forward-sexp'
or `backward-sexp'.  These commands should be bound to some convenient
keystroke, since they are just so useful.  

In general, I think the answer is probably either "no" or "there's a
better way"... but using a trick I just learned from David Kastrup
here, how about C-SPC C-g <navigate to wherever you want>, then C-u
C-SPC (or alternatively C-x C-x), to return to where you set the mark?
(C-g is only inserted in this sequence to prevent the region from
being highlighted in `transient-mark-mode').

(Sorry that this advice has nothing to do with your mouse wheel, but
you could probably set things up to set/restore the mark etc. all with
the mouse - then you'd be totally set!)

Hi Olive,
You should find this thread interesting: "Emacs text cursor position" 
from 23/01/2005, in which a very similar question was asked. Although, 
unfortunately, no (ready-to-use) solution was provided.
