I don't know if it's been addressed before, i would like to assign key bindings to the sas markers (prograde, retrograde, radial etc...) of the nav ball, i looked into the game settings but i haven't found anything useful, i'm planning to build a custom controller so i want to stay as mouse-free as possible, i know that it's possible with some arduino wizardry, but for my progect i will use a simple HID board, so, is there a mod for it?
