Preview Properties
Preview thumbnail images and the background area between thumbnail images both have context menus.
Thumbnail preview actions
Right-click and drag to change the view.
This does not have much affect if the preview object is a sphere, but if it is a cube, cone, or other shape, rotating the view or object shows the preview object from different viewpoints.
Right-click to display a context menu.
Double-click to display a larger preview window below the thumbnails.
Drag the preview thumbnails to reorder the list.
Press the Ctrl key while dragging to duplicate a material.
Double-click the larger preview to open a floating window that can be resized to get a higher resolution view of the preview.
This window has all the same functionality as the original preview image including the context menu and the ability to drag and drop onto other materials or objects in the model.
