The left mouse actions in the 3D window affect either the camera or light positions (depending which is selected in the drop-list on the camera/lights page)
| Left Drag: drag the camera/light up or down (left - right movement is ignored) |
| Shift Left Drag: camera only - zoom the image (drag right to increase size, dragged left to decrease) |
| Control Left Drag: rotate the camera/light position |
Right mouse actions in the 3D window are only effective if a background image is loaded which is bigger than the 3D window.
| Right Drag: drag the image in the 3D window |
| Shift Right Click: centre background image |
| Control Right Click: toggle between 'stretched to fit' and full-size image |
From v9.0, there is the additional facility:
| Shift Right Drag: zoom image (drag right to increase size, dragged left to decrease). Shift right click returns are the image to full-size |
