How would you track the mouse buttons in Fortnite if you have a Razer Deathadder?

How would you track the mouse buttons in Fortnite if you have a Razer Deathadder?

Front thumb button: roof, thumb button on back: wall, mouse wheel press down: stairs.

Are you good at Fornite?

I have them too. Just have a pyramid on thumb button below.

Stairs = C

Wall = V

Soil = B

Is actually pretty good. Have not kept a blank thumb but what the hell.

Is even somehow difficult to quickly choose the pyramid because I'm not used to pressing the thumb key.

At least I would not call myself a bad person
