That's no moon!
Above the Fn keys we can see a SideWinder symbol which brings up the Intellitype Pro software to allow you to quickly configure macros and assign functions to the Sn keys.
A running man key acts as a key lock function to save you having to hold down one key for a prolonged period of time. It also works for any combination of keys being pressed at the time.
There's a record macro function that lets you assign macros on the fly and in-game to any of the Sn keys.
Then you have a preset selector switch, allowing you to jump between three presets of recorded and assigned macro settings on the keyboard.
After messing about with the macros and the media controls, I figure it's time to get gaming.
The best test for all these macros is World of Warcraft, so back in I go to the addiction. A few dungeons later and a couple of levels up, it's clear that having the macro functions really help with games with grind.
The keys are responsive and have a nice solid click, so you can always be sure of when you have or haven't pressed it enough. The spacing is about right if you are used to a full sized keyboard.
A neat feature of the backlighting on the keys is that the WASD keys have a series of dots on the side facing the user, so they can be easily located in dark conditions.
The macro keys down the left hand side are also backlit in orange rather than red to help define the edge of the regular keyboard, so your hand position remains over the WASD and not too far to the left to press TAB and Capslock.
