Is there any way to zoom in and out?

is there a zoom tool because i just want to see it clearer. by the way i have a laptop so i don't have a mouse scroll thing.

Alt+right mouse (drag) do the trick.

(I assume you are talking about navigation in the Unity Editor).

To zoom in and out in the scene view you can either use the mouse scroll wheel or press Alt+right click and then move your mouse.

Just change the main camera projection size
