The FOG manual's guide to keyboard commands says to zoom in and zoom out using the + and - keys. But my game isn't responding to those keystroke commands. Am I doing anything wrong? Using a Dell XPS13. Is there any other way to zoom in and out? Some adjustment either within the game or on my machine.

As a follow up on this.

I also have a Dell, I also have no mouse wheel, but would like to zoom.

Is there any hope here?

Same for me, I can´t get zoom to work
