How to set the mouse wheel scrolling speed in IntelliJ?

Question

Is there a way to set the mouse wheel scrolling speed for an editor window? I think it's too fast. I'm running IntelliJ IDEA 8.1.4 on Mac OS 10.6.2.

Answer 1

There is no option for this feature

Answer 2

To get a precise scroll (very useful when comparing files), you can use Smooth Scroller plugin: https://plugins.jetbrains.com/plugin/8246-smooth-scroller

To scroll in larger steps, use Fast-Scrolling plugin: https://plugins.jetbrains.com/plugin/7573-fast-scrolling

You can use both plugins together, to make mouse scroll smooth and precise by default, whereas scrolling with CTRL key, makes it scroll faster.

Just in case any windows 10 users stumble upon here.

Settings -> Mouse -> Choose how many lines to scroll each time

Set to 3.

Answer 4

Ok this is no answer for Mac OS, but for Linux. I didn't find the relevant question for Linux yet, so I give a try here.

In IntelliJ IDEA 2018.1.1 when I go to editor or console, mouse wheel scrolling means this: go down or up in the list by 3 lines for each single wheel "snap in". I had no luck to find a an option in IDEA itself to adjust this number.

In my case this is too slow. To get this fixed, I did:

sudo apt-get install imwheel

Add the following to ~/.imwheelrc, e.g.:

"^FocusProxy$"
None,      Up,   Button4, 10
None,      Down, Button5, 10

"^Firefox$"
None,      Up,   Button4, 3
None,      Down, Button5, 3

...

Please consider, that 10 is multipled by IDEA's 3, so the resulting wheel speed is 30.

Then, kill & restart imwheel with imwheel --kill.

Kill & quit (finalize the process) with imwheel --kill ---quit

FocusProxy is the window class, which was told to me by kill & restart in debug mode imwheel --kill --debug

I was uncheck in UI Options/Smooth scrolling, and i feel like it.
