Help with controls-related mod

[Jason1923]

Hi, I want to add custom entries in the Controls menu. Is this possible? I want to implement an "Inventory Use Self" keybind (it's present for controller but not for keyboard IIRC), which functions exactly the way it sounds: it will consume stuff like food, healing, a blueprint, etc.

If not, is it possible to add/edit controls from a mod config menu? I want the user to at least be able to customize the keybind through a normal menu instead of an in-game pop-up (or having to use a hardcoded key).

Some other questions I have:

1. Where are the controls stored?
2. Are there any resources that you recommend I look at?

Finally, I am new to DS modding but I am comfortable enough to implement this mod with some guidance. However, I am also willing to pay someone else to create said mod (let me know and I'll give you the details). Thanks for reading!
