your screen. This is a toggle keyboard shortcut, meaning that if you press Ctrl+Y or Command+Y
again, the preview is turned off. You may not see a difference in the image, depending upon the
range of colors, but the title tab indicates that you are in CMYK preview mode by displaying
/CMYK after the title of the image.
