Getting Started: Description - Main Window - Working With Images - Navigation - Editing Images - Entering your licence key
Navigating between images
Pressing the OK button saves any changes and moves to the next image. Normally, pressing Enter has the same effect as OK. The one exception is when you are editing text, because then Enter starts a new line/paragraph. In this case, press Tab to move to the OK button, then Enter.

After the last picture in the directory, the program asks whether you want to move to the next directory. Press Enter again to move to the first picture in the next directory.
The keyboard shortcuts Alt+Up Arrow and Alt+Down Arrow move between pictures in the current directory. If the focus is in the image list, you can also use the arrow keys normally.
Navigating between Folders
The Prev and Next buttons move to the previous and next folders. You can also use the keyboard shortcuts Alt+Right Arrow and Alt+Left Arrow.
