Add option to not map Special button

[Sango916]

The Map Special Buttons causes a problem that every time a button is pressed, it either performs an extra action or is not recognized by the game.
So I would like to disable it, but I can't find the option to do so.
I was able to disable the Capture button by setting it to 0 in the settings file. However, all other buttons cannot be disabled even if they are set to 0.
So, if there is no way to disable it, I would like you to add a function to disable it, and if there is, I would like to know how to do it.
