React to ScrollWheel in from-event

[wedi]

Hi, I got into the habbit using ctrl + left/right scroll to switch desktops. Unfortunately, I still haven't found a way to achieve this with Karabiner Elements.

Does anyone know a way to make this work? I am looking for a way to react to horizontal ScrollWheel events. As to-event this is documented but unfortunately I haven't found anything about a correspondig from-event.

Thank you!

In the old days it used to work this way:

<autogen>
    __ScrollWheelToKey__
    ScrollWheel::RIGHT, MODIFIERFLAG_EITHER_LEFT_OR_RIGHT_CONTROL,
    KeyCode::CURSOR_LEFT,  MODIFIERFLAG_EITHER_LEFT_OR_RIGHT_CONTROL,
</autogen>

#1066 describes exactly how this was achieved earlier:

The previous version of Karabiner allowed one to reference ScrollWheel::Left and ScrollWheel::Right in the "from" field of mappings. I have not been able to find any documentation on how to do this in Karabiner-Elements.

In Karabiner-EventViewer I just see a "ScrollWheel" event come in along with "misc" data: "dx: -2.10 dy: 0.00 dz: 0:00".

Hey I would love to know this as well, using left/right scroll to map to back/forward buttons would be pretty awesome.

Just stumbled upon one more related issue: #1314 There is a simple modification TO a mouse scroll event but not FROM:

From key

To key

Is there absolutely no solution to remap left/right scrolling? Not even a slight hint? What a pity.

Yes i found that in old versions there is a way to do that which i really need that with my sculpt mouse.

Thanks for the hint! Unfortunately this is a configuration for the legacy Karabiner (as one can tell from the XML format) not the current Karabiner Elements. The new version has no obvious support for this and I couldn't find a workaround yet.

Bump: wouldn't mind being able to rebind scroll wheel to perform certain actions.

I'm trying to zoom in and out using a scroll wheel in Zeplin, so I need to rebind wheel up to ⌘ + and wheel down to ⌘ -.

[calvinwyoung]

Has anyone found a workaround for this? I'm also looking for a solution right now.

[zgeist27]

I'm looking for this, too.

[VVakko]

I miss this feature too.

To feed the stale bot, I'll chime in that I'd also love for this feature to be implemented.

[chavlji]

I also desperately need wheel up/down as from key. I need it to:

• switch tabs with right mouse button down + wheel
• switch apps with mouse button 4 down + wheel I'm begging you please!

Still a pretty significant missing piece of functionality.

[krzysztofwolski]

As a new MS Sculpt user I'm also interested in this func.

[RainbowTraveller]

Yes. Need ability to scroll using scroll wheel....!

[piotrtobolski]

Any news?

[stianhoiland]

I would like to see this, too! I'm looking to change what happens when the scroll wheel is scrolled up or down, for example to remove acceleration.

[SolusCado]

Are there plans to implement this support?

I used to use Razer's Synapse software with my Razer Nostromo to - among other things - control the system volume from the scroll wheel. As of now (in Catalina's latest beta), Razer Synapse doesn't work - so I'm finally getting around to remapping everything with Karabiner Elements instead. This ALMOST works great (better than Synapse, in terms of speed and reliability).

The problem of course is that Karabiner Elements doesn't seem to support scroll wheel events. Is there a technical reason for that? In the meantime, I'm using BetterTouchTool to at least let me control volume through a scroll wheel+modifer key combination, but it isn't as smooth as what I had before, and what I would imagine we would get from KE.

So, for what it's worth... +1 on this request!!

[yanickxia]

waiting for it....

[Vxider]

I'm looking for this, too.

[fogrid]

Yea, I would like this feature too - I really want to be able to zoom with the mouse

[prasskaly]

I would like to have the feature of Ctrl+scroll up/down to zoom in/zoom out. Firefox supports this mode for macOS, but I want it to natively run in all apps that will be only possible with a tool like Karabiner.

[kerryj89]

Since it's already understood in the to-event it should be trivial to understand from the from-event, no? Of course you and I both know things aren't always as simple as they seem. Still, some acknowledgement from the maintainer would be nice as to whether or not support for this will be coming. As of now I'm using BetterTouchTool which works for me (was already running it).

I'm missing this feature to reverse my mouse scroll without reversing trackpad scroll.

[donmurdoc]

I'm going crazy trying to do this!
