You can use the arrow icons of the toolbar or the PAGE DOWN and PAGE UP key to load assets in the window. When there is more than one asset on-screen, the asset that is changed is the one that is marked as selected by a light green border and a big check mark symbol. If none is selected, the entire group of previewed assets is replaced by the next group. If one is selected, the PAGE DOWN key changes the asset to the next one in the collection and the PAGE UP key changes it to the previous one. You can also use the mouse wheel to scroll through.
TIP: Loading Another Preview
If multiple assets are displayed in the Preview window, a single asset can be loaded into more than one preview area, enabling you to pan, zoom and examine it in detail. To load another preview in a preview area, select the preview area and use ALT+Mouse Wheel.
NOTE: Linked preview images are navigation locked, i.e. they never change position and can’t be replaced with other assets via the PAGE UP / PAGE DOWN keys or scroll wheel navigation.
