Camera rotation movement messed up

Okay, so I’m very new to blender, and I was making my first 3d character, when I pressed some kind of hotkey, and now when I rotate my camera (not the mesh), it doesn’t rotate around the axis of the selected objects, but on its own.

I tried reverting to factory settings, and that didn’t do anything. When I stated a new project with the default cube, it worked fine, so I’m guessing it’s in the specific .blend file.

Here’s the blend file:

When you open it up, try rotating the camera around the object, and see what happens.

Thanks in advance,

Sounds like you want to change the pivot point. Use the drop down list on the 3d view header
