"One of those choices is to control how you want the LEDs to appear in color, intensity and pulsating or not. You can even have more than one color led on at a time on the pad itself. The mouse and mouse pad are separately adjustable. You can set these to whatever color scheme suites your fancy. These LEDs serve another function other than for looks, such as when making macros, the LEDs will flash or switch on or off depending on what you are doing at the time. Also on this tab, you can adjust the resolution from 400 dpi all the way to 4000 dpi. It is also adjustable on-the-fly, even while gaming by using the buttons on the mouse. Then, below this, you can adjust the sensitivity of the joystick emulation. In order to use the mouse as a joystick, you press the Ctrl key on your keyboard and the mouse button number five."
