Navigation in the view panel is possible with the navigation buttons in the view panel's upper right corner or with the mouse. To navigate using the buttons, press a button and drag with the mouse while keeping the button pressed. To navigate using the mouse only, press the Shift button and drag with the mouse over the view panel: The left mouse button rotates the view, the middle mouse button moves the viewpoint in the viewing plane, and the right mouse button makes a dolly movement along the viewing direction (or a zoom for a view camera with parallel projection). The mouse wheel works similarly to the right mouse button.
