having a moment here in gnome
to everyone pointing out that this is for touchpads;
a: it's awful on that too
b: note the mouse in the example given
Thanks for explaining, because based on the displayed pucture and the direction arrows in the content window you would think it's the other way - scrolling mouse wheel up to move content up.
Confusing way too display it, but I guess whoever is in that settings window knows what they're on at the moment and that it would invert it.
