You can control how you view your scene by switching and moving cameras.
You can control which camera you use in a view panel to display the scene, and how you move that camera around. No matter which camera you choose (default perspective or orthographic cameras, or a camera rig you have created), you are always looking at your scene through a camera in a view panel.
Watch the video below for information on how to navigate with cameras in a view panel using the different tools and commands in the View menu.
