Basically, I'd like to be able to press some key or input to switch the Tartarus from one set of functions to another (ie. the 19 keys are great but 38 would be better). So in my mind, if I can use the Fn key on my keyboard or ctrl or alt or shift or whatever, it would tell Tartarus to do something different for the 13th key than the bland 13th key without that addl input. I found an article on Razer's website about secondary functionalities, but it seemed out of date because I couldn't reproduce it. Thanks.
