Slider scrolling with mouse wheel?

[Lane23499113pawo]

Windows 11 and LRc.  I thought I used to be able to move sliders using the wheel on my mouse. Now I cannot. Am I doing something wrong?  Also in Camera Raw? Thanks

[johnrellis]

I just tested LR 13.0.1 and LR 6.14 on Windows, and LR 13 still works the same in my configurations. You need to click the teardrop on the slider, and if you move the mouse pointer too far away from the slider, the slider's label will grey out and it will stop adjusting the slider.

To add to what johnrellis started, a screenshot, with "teardrop' circled:

Thanks. But I have tried that repeatedely, in LR, PS and LRC. Clicking the teardrop and scrolling. When I click it, it does light up, but greys out as soon as I let go of the left click mouse button.   Has to be a preferences setting or something, but I sure can't find it?

There's no preference controlling the use of the scroll wheel. But LR might have corrupted the preferences file. Try resetting LR's preferences:

LR sometimes soils its preferences file, and resetting it can fix all sorts of wonky behavior. That article explains how to restore the old preferences if resetting doesn't help.

Thanks. Haven't tried that yet, but I did connect another mouse - scrolling sliders with wheel works fine - but only in LRC, not in PS or LR (cloud). Any idea why?

[johnrellis]

No idea, unfortunately.

I tried resetting preferences as you suggested.  Still can only scroll sliders in LRClassic, not PS or Lightroom.

Perhaps, for PS, see:

and/or

(yes I know, one of those annoying people that move their mouse all over the place like using hands to talk, and is very slow to get to the bloody point)

Did you figure this out? I just updated my lightroom and now I cannot scroll either. I only edited this way so it is driving me crazy!

[Lane23499113pawo]

Nope, I never did and it drives me nuts too. If you figure it out, please let me know.

Note that moving the slider with the mouse wheel only works on Windows, not Mac.

[Lane23499113pawo]

Thanks. I am using windows

But why only for Windows users ??
I just switched from a Windows computer to a Mac, and i don't understand why the mouse wheel doesn't work on Mac ?!?!

[johnrellis]

@davidd37970807: "But why only for Windows users ??"

It's been that way since the beginning. My guess is this was an accident of the way Mac LR was initially ported to Windows, e.g. the Windows programmer used a standard UI component that enabled the scroll wheel for sliders by default. It's certainly technically possible to do this on Mac, but perhaps the engineering cost was always higher than what the product and engineering managers wanted to spend.

There is a longstanding feature request to which people should add their constructive opinions and upvotes:

(You've just done that.) There was a very old feature request that didn't get migrated from the old feedback forums:

When Lightroom was originally under development there was no Mac API support for slider scrolling with the mouse wheel. This may have changed in more recent times, but the Development team may not have picked up on it.

If you haven't already done so, Upvote the existing feature request at https://community.adobe.com/t5/lightroom-classic-ideas/p-mouse-scroll-wheel-enabled-for-mac/idi-p/13...

Capture One has supported using the scroll wheel on both Mac and Windows to change sliders since at least Capture One 4 (2008) -- see page 111:

I'm reporting what we were told by the engineers developing the application. That was back in early 2006, when the Windows version didn't even exist. 

The first public beta for Mac was released on 9 January 2006 and the first public beta for Windows on 18 July 2006.

[johnrellis]

Right, that's not inconsistent with Capture One offering it in 2008.

See below linked thread from 2013. It provides some additional information, albeit not a definitive explanation.
