I've tried looking for the button or anything, but it is impossible. I'm new to blender, so please when you say the answer explain it in an easy-to-follow way. Problem: I have an object that I want to view from different angles, when I press middle mouse to move the camera it will rotate the camera around and not rotate around the object I clicked on. How do I switch/fix this? I DO NOT WANT TO CREATE AN ANIMATION. All the videos or help forums I try to look up online is for creating an orbiting animation, but I don't want that. Here is a picture to explain what I mean. Currently, when I press middle mouse to move the camera it will rotate around itself, showed by the gray arrows. What I want is to get the camera to rotate around the object shown by the green arrows. It is probably some simple button to press to switch these modes, but this is so annoying that it is so difficult for a new user to figure out on their own.
I'm not entirely sure what you mean by "camera will rotate around itself", but I'm guessing it's that you want to stay inside the camera view, but still control the rotation of the scene. For that, you can enable the Lock: Camera to View option under the N > View > View Lock panel.
