You can still click on the sides of the page (left/right side) to turn pages with a mouse if that "Treat Mouse Click as Pedal Press" is off. Enabling that setting will stop the mouse from interacting with the UI while viewing scores. I'm not sure there are really any other changes that matter if you don't have a touch screen, as a mouse should work identically to a finger when it comes to touch interactions. The only thing that is more challenging is zooming as you have to hold CTRL while scrolling a mouse wheel.
