Menu
The Main Toolbox is located at the top middle of the main window. It includes 2 items:
 
 
1. Pan Tool
 
This item is marked with an icon depicting a hand. It is on by default after you launch the program. If you are using another mode, you can switch the Pan Tool on, by clicking the Pan Tool icon or pressing A on your keyboard.
When you move your mouse over an image, the standard cursor changes to a hand. Using this tool, you can freely move across your image, by holding down the left button and dragging your mouse. This option may be very useful when you want to take a close look to specific details of your image. Also, you can zoom in or out of an image, by turning the wheel of your mouse up and down.
 
Note:  The Pan Tool is active only if an image cannot be fully displayed in the Preview Area.
 
2. Zoom Tool
 
The Zoom Tool icon looks like a loupe. To activate this tool you need to click the icon or press Z on your keyboard. When you move your mouse over an image, the cursor changes to a loupe. Using this tool, you can zoom in of your image each time you left click on it and zoom out with a right click. The zoom step depends on a current scale. The more a scale, the more a zoom step.
