Mousewheel Binds
This mod lets you assign custom actions to the mouse wheel.
You can change the keybind used to open the menu under Miscellaneous.
When you open the menu, you’ll see separate entries for Scroll Up, Scroll Down, and Middle Mouse Click.
On the Minecraft Action page, every available action, including all in-game settings, is listed in alphabetical order.
With Keyboard Input, you can assign any letter, number, or symbol key. Your keyboard inputs will be saved under this option.
