"The Dominatrix features the usual combination of left and right mouse buttons, coupled with a scroll wheel which can also be pushed left and ride for horizontal scrolling (or other functionality if you so wish). Below these main buttons are a couple of additional features - This pair of buttons are available to cycle through the Dominatrix's various DPI settings so that its sensitivity can easily be changed at any time, and to switch between the various custom button configuration modes (up to three) which you can set using the supplied software. We'll cover this in a little more detail later."
