How can I make Emacs mouse scrolling slower and smoother?

Solution 1:

You can control the amount in variable mouse-wheel-scroll-amount (in mwheel.el).

EDIT: E.g. Add (setq mouse-wheel-scroll-amount '(1 ((shift) . 1) ((control) . nil))) to your .emacs for 1 line at a time.

I also have (setq mouse-wheel-progressive-speed nil) in my .emacs which I think is nicer behaviour.

Solution 2:

I use breadcrumb to leave a trail around a buffer or all buffers.

Drop the breadcrumb, go look at whatever you want/need, then jump back to the breadcrumb. Here's what I have things set to, FWIW:

(global-set-key [(f6)] 'bc-set)
(global-set-key [(shift f6)] 'bc-list)
(global-set-key [(control f6)] 'bc-previous)
(global-set-key [(meta f6)] 'bc-next)
(global-set-key [(shift control f6)] 'bc-local-previous)
(global-set-key [(shift meta f6)] 'bc-local-next)

Hope that helps.
