A three-button mouse (with a wheel) is the best way to control the camera in Preview Tools.
Click and hold the left mouse button to move the camera left, right, up and down on the X and Y axes.
Click and hold the right mouse button to move the camera forwards and backwards on the Z axis.
Click and hold the mouse wheel to rotate the camera on its own axis (up, down, left and right).
Navigation modes
You can switch navigation mode from Drag (explained above) to Right-click by clicking on the walking man icon. A Right-click will enable you to jump to the position indicated by the blue circle.
TOP TIP
Use Drag mode when setting up a smaller section of your gallery. Toggle to Right-click when you need to move around the space quickly. Don’t worry, movement will quickly become second nature.
