How to use the mouse cursor with keyboard?

[RusticCraftsman]

Hello, im using this mod, so you should be amazed by that, as you said on the readme.
Do you have any recommendations of how to use the mouse cursor with keyboard? is that an app or your mod applied with some added code?
also, do you have any config i could borrow from ya, like your whole keybind settings (from the game and/or the mod) so i could just start playing?
