I'm playing Fortnite on PC and recently hit the "Alt" key to place traps. My problem is that Windows 10 sometimes just tabs out of the game when I press Alt. Does anyone know why this is and how can I change that?

I can't tell you why that is but you could just put the case button on the right mouse button.
