It doesn't actually capture your screen, but rather saves the Cairo surface to an image. The path to the image and some other options can also be configured in the config file. By default, Print Screen can be pressed in Normal mode with no modifier to take a screenshot. The default location is the user's home directory, and the file has a date attached to it. Of course, this can be changed as well.
