Currently, we’ve got these options:
Personally, i think it’s not bad to have some more.
Like:
- Spacebar + Mouse Wheel
- Ctrl + Shift + Mouse Wheel
- Ctrl + Alt + Mouse Wheel
- Shift + Alt + Mouse Wheel
- Ctrl + Alt + Shift + Mouse Wheel
- Ctrl + Shift + Spacebar + Mouse Wheel
- Ctrl + Alt + Spacebar + Mouse Wheel
- Shift + Alt + Spacebar + Mouse Wheel
- Ctrl + Alt + Shift + Spacebar + Mouse Wheel
Additionally, my scroll wheel is currently broken.
(Would’ve been easy to replace if it wasn’t a multi-button trackball mouse where only the scroll wheel is broken.)
Don’t know if it’s possible, but can we have an option to replace the up and down signals of a scroll wheel with different kb keys we choose?
For example,
instead of a Ctrl + Mouse Wheel,
It would be: Ctrl + up arrow / down arrow.
Or maybe a: Ctrl + page up / page down.
Lastly, or maybe a: Ctrl + Mouse move up / Mouse move down. (This would be my most preferred. Because trackball. 
)
