While browsing through youre image collection sometimes you may want to look up an image in a different folder or album. To do so simply press SHIFT+F10. Now the current image will be marked with a green frame.
You can change the folder or filter, even close the application and restart it. When you press CTRL+F10 the image will be located and displayed, if it is part of the view.
This feature is also very useful to mark the current position while browsing through a large set of images and later return to this position. This feature requires the fotoARRAY license.
