Obviously the G19 keyboard is very customizable. The keyboard has 12 macro keys, an LCD screen that can be set to display a wealth of information, and a backlight that can display most any color, although some colors display better than others. Additionally, the ability to change between three profiles at the touch of a button is key. If you have several games you switch between, you can make three separate profiles, complete with different backlight colors, to handle all your custom key macros.
