Linking Panels
In Fullscreen Previews of multiple assets, two or more panels can be linked together for synchronous zooming, rotating and panning.

1. Click the icon on the statusbar of every panel you want to link, OR
 CTRL-click /   CMD-click any of the icons to link all panels in the fullscreen preview.
In linked panels, the icon is highlighted.
To unlink panels, i.e. to exclude them from synchronous zooming, rotating and panning:
 
1. Click the highlighted icon of every panel you want to unlink, OR
 CTRL-click /   CMD-click any of the icons to unlink all panels in the fullscreen preview.
NOTE: In fullscreen previews of single assets, the icon is not displayed.
