Change the default Input for Widgets?

Development Programming & Scripting Blueprint
1

When widgets are created in the game, you can switch buttons with arrow up/arrow down and “click” with spacebar/enter by default.

But i need to change these default input buttons to "up/down with the mouse wheel and “click” with the middle mouse button?

Hope someone could help me

Thanks

Try this, and implement it in Hud: Mouse Wheel Axis | Unreal Engine Documentation

I have to change the default input, because they’re addressed directly.

In that case if it is not in. Project settings, you would have to use c++ which I could not help you with, sorry mate!
