I found it in the settings twice, but now I can’t find it.
Trying to find it in the help - the results are only answers in the style of “you can scroll one, the other”.
People, please tell me how to enable scrolling in darktable? Where is this item in the settings?
darktable 3.8 user manual - miscellaneous see that section.
Thank you. Found it 
You have the box in the preview as well if you are zoomed…that can be faster…
Ah maybe you mean scroll with the mouse wheel the module panels rather than the sliders??
Which ever I think if hold ctrl-alt you will get the opposite way to work so you don’t have to toggle
I was just putting a program on for an aunty.
My eyes are looking in different directions because of myasthenia gravis myself))), but I wanted to show her the program.
Thank you, again
