Scene editor camera angle

Hi guys, really dumb question

How the heck do I get my scene camera where I view my objects and stuff to become isometric again? The camera always starts off isometric, with Y pointing up, X pointing bottom left, and Z pointing bottom right. Then when I click the XYZ gadget at the top right it becomes XY, XZ, or YZ view. How do I get it to become isometric again??

For context, I am a new user doing the rolling ball tutorial

Click the cube in the center.
