How to assign mouse wheel custom input?

[jarcionek]

This wiki says that mouse wheel doesn't work for custom inputs: https://wiki.factorio.com/Prototype/CustomInput

If I assign key sequence "mouse-wheel-up" or "MOUSE_WHEEL_UP" - the game doesn't recognise it. However, if user assigns this control themselves, everything works as expected.

Is there a way for a mod to assign it?
Is this wiki outdated?
Is it a bug?

Not a bug, see 42473. It works as described on the wiki, the input does not work if the mod sets it to mouse wheel in the prototype.

I came across the issue you linked and it seems that this problem does not exist any more.

- If I manually assign mouse wheel to the mod custom input - it works.
- If another action has mouse wheel assigned to it - both actions get triggered.

I don't understand why mod is not allowed to assign the mouse wheel, but if the user does it themselves it's ok?
