Basically what the title says. Because "shift" scrolling uses the sneak keybind but "ctrl" scrolling is hardcoded to ctrl instead of using the run keybind, you can't set the abacus in increments of 1 or 0.1 if you set your sneak key to ctrl.

I am also encountering this issue from having sneak bound to Ctrl and sprint bound to Shift.
It would be nice if the mod added a keybinding for the modifier to give players more configurability.

I don't think this is a keybind problem - the "holding ctrl" thing is just checking if the modifier key is being pressed. Which means command on mac, and ctrl on windows. So you can't rebind that, not really...

Which is why it should probably be the crouch and sneak keys
Since some people (like me) bind spring to shift and crouch to control

that's up to petra to decide then, not me

What do you mean by the "crouch and sneak keys?" Those are the same key.

... The irritating thing is that there's not any easy fix to this, because if I add a remappable keybind for the "ctrl" behavior, then it will conflict with anyone else trying to use that key, including vanilla's sprint keybind.

I suppose a solution is to have some config option to remap it to a hard-coded different key, like alt. To be honest, that might be the best solution even though it sucks. But I'd like your feedback on what to do.

sorry i meant that people (like me) like to swap the crouch and sprint (wrong s word)
so i think a better option would be to detect if holding the sprint key instead of checking ctrl specifically (which is the default value for the sprint key)

Responding to this as a hope to remind people of it since it's been here awhile!
I find this quite annoying as a ctrl-sneak user.

Isn't there way to make it a remappable keybind for ctrl without having it conflict with anything? I've been making modpacks for awhile and have had many scenarios in which multiple actions were bound to one keybind and they would just all happen at once. Though, I have also had scenarios in which none of the things would happen... I had assumed there was just a way to specify the behavior of how it works.

Though, allowing the user to remap the bind themselves would be very very preferable. Every user can get used to their own bind themselves. I'd say alt is the best default if you can't make it overlap with ctrl.

As another shift for spring ctrl for sneak, I agree that's an issue.

If making an actual keybind is an issue, then yeah a line in the client config to switch it would be good enough imo. Could probably hardcode it to 3 values so users can choose between ctrl, shift, and alt, something like that.

This is a problem for me as well.
Please make make the default behaviour use the sprint key instead of the control modifier.
It wouldn't change anything for shift-sneak users as ctrl is sprint by default, and would allow easy customisation for anyone else.

If this isn't implemented yet, we should fix it for the 1.20.1 release.
