Overlay Windows


Overlay windows allow you to view and manipulate the layers in the project. The main layer window is the Overlay window, but each layer also has an image window and/or feature window associated with it. The Overlay window allows you to view multiple layers on top of each other. The Overlay window can be toggled on and off from the View menu. The image windows and feature windows associated with a layer, on the other hand, are useful for viewing two or more layers side by side. These windows can be enabled by the context menu in the Project window.

You can move around in the overlay window with the keyboard by pressing the A (left), D (right), W (up), S (down), Q (zoom in), and E (zoom out) keys. You can also move around with the mouse. Hold down the middle mouse button to move up, down, left, and right, and zoom in and out with the mouse wheel.

When a layer window has the focus, then you can use the arrow keys to move around. Each layer window has a ruler in the lower-right corner that gives you a sense of scale. If you right-click anywhere in the overlay window, then the following menu will pop up:

  • Go to
