Simple navigation within schematics is done by right clicking and dragging. This will pan the schematic. Zooming is achieved by holding Ctrl, right clicking, and dragging or by holding middle click and dragging. Depending on the computer, touchscreens and trackpads may or may not work intuitively (pinch to zoom, 2 finger drag to pan).

Layouts have three fundamental views:
Planning view
Layout view
3D view
...
Simple navigation within 2D layouts is the same as schematics. Panning and zooming are the same as above. In addition, the whole board can be “flipped” by hitting Ctrl + F.
Within 3D view, the shift key is used to access view rotations. When holding shift and right clicking on certain parts of the control sphere you will be able to rotate and tilt the view. Simple panning and zooming are again, the same as schematics and 2D view. Hitting Ctrl + F will flip the board about the cursor.
