Mouse Scroll.

Mouse Scroll.

[Daniel]

Hi All,

I want to scroll just one line when I spin the mouse wheel. I know I
can do it with SHIFT key, but it is tedious to hold SHIFT every time.

I have found mwheel.el, and modified like this:

(defcustom mouse-wheel-scroll-amount '(1 ((shift) . 5) ((control) .
nil))

Also, I byte-compile-file mwheel.el, but it does not seem to work.

In addition, I added this in ~/.emacs
;; Scroll
(defun up-slightly () (interactive) (scroll-up 5))
(defun down-slightly () (interactive) (scroll-down 5))
(global-set-key [S-mouse-4] 'down-slightly)
(global-set-key [S-mouse-5] 'up-slightly)

(defun up-one () (interactive) (scroll-up 1))
(defun down-one () (interactive) (scroll-down 1))
(global-set-key [mouse-4] 'down-one)
(global-set-key [mouse-5] 'up-one)


(defun up-a-lot () (interactive) (scroll-up))
(defun down-a-lot () (interactive) (scroll-down))
(global-set-key [C-mouse-4] 'down-a-lot)
(global-set-key [C-mouse-5] 'up-a-lot)

But, it does not work also.

What I want is just to scroll only one line when I spin the wheel. How
can I do this?

(BTW, why emacs is so hard to use? It is very less intuitive to use.)

Have you put (mwheel-install) in your .emacs?

I think the reason your code doesn't work is that, using Emacs 21.3,
[mouse-4] and [mouse-5] only represent the wheel on X11, not on MS
Windows.  On MS Windows the signal is different.

On the current CVS version of Emacs this inconsistency has been
removed and your code would work fine.

Sigh, It's a long story.

- No, I am using Ubuntu 6.10 (Edgy), and using apt-get, I installed
emacs-snapshot (version 22.0.50.1).

- As I said, I am not using MS Windows.

- Yeah, long story. However, I am trying to use it for work. Thanks.

   What I want is just to scroll only one line when I
   spin the wheel. How can I do this?

you found the right variable but you did not find how
to set it.  try placing in ~/.emacs something like:

(setq
 mouse-wheel-scroll-amount
 '(1                       ; no mod
   ((shift) . 5)           ; fast
   ((control) . nil)))     ; screen

then move the cursor after the close paren and type
`C-x C-e'.  alternatively, that particular variable
can be set using the customization interface.

   (BTW, why emacs is so hard to use? 
   It is very less intuitive to use.)

emacs is disciplined; discipline is hard.

Just curious, what do you mean? Seems to me that, for a terminal-based
app, Emacs is pretty easy to use -- you just need to remember or else
look up a number of key-combos. The docs are good, the integrated help
is good. Haven't really tried elisp though.

   I use this; just change two/2 to one/1:

(defun down-two ()
  (interactive)
  (scroll-down 2)
)

(defun up-two ()
  (interactive)
  (scroll-up 2)
)

(global-set-key [(mouse-4)]  'down-two)
(global-set-key [(mouse-5)]  'up-two)
(global-set-key [(mouse-6)]  'down-two)
(global-set-key [(mouse-7)]  'up-two)

...

   It is not hard to use.

Thanks, thi,

It really help. Thank you. I didn't even know about 'C-x C-e' .

Thanks, Johnson,

But, in my case, it seems that my global-key for mouse wheel is prior
to the .emacs. That was weird, but now I think I solved. Thanks.

If you want to use it as it comes out of the box then it's very easy
to use, it works like the editors that come with common operating
systems.  It's just much more powerful and has slightly different
keys.  Writing elisp and adding support for new features isn't even
that hard either, if you're OK with learning another language.

There are problems though.  Keymaps currently present a small problem,
since the only way to modify them is through elisp.  This isn't hard
in simple cases but often the exact specifics of how they should be
used are difficult.

Most users I think act like myself when they get a new program, they
use the keys that it uses, another small group of users immediately
start rearranging the keys.  I think the OP is one of this second
group who end up wondering why everything is so hard.  Loads of the
enquiries from newbies on this newsgroup are from trying to rearrange
keys.

All that said, I can't complain, if I was really bothered I'd write
some code to make it simpler.
