more info on additional layers:
you can set one of your keys to act as the 'fn' key - which will allow you to use an additional layer.
under the 'option' bar, check enabled for "ScrollLock LED -> FN LED" and "FN Lock" (might as well enable N-key rollover as well)
now, under the 'Key Test' bar, you will see an area labeled "Keyboard Matrix Mapping" in red, and to the right, you'll see Normal, Function, and Numlock checked. for your base keymap layer, go ahead an uncheck Function and Numlock options, and program/map the keys that you want with only the "Normal" option checked off.
For the additional layer, uncheck the Normal option, and check off the Function option - and repeat (map the keys that you want for function layer). the keys that you program for 'Function' will be the active keymap when the 'FN Lock' is triggered - pretty similar to how Poker 2 layers are used, in a sense.
In order to permanently have Fn Layer [ON], hit the FN key three times until you see the Scroll Lock indicator light on. To return back to regular layer, just hit the FN key once (the scroll lock LED will turn off)
might be confusing when you read this.. but once you actually start mapping the layers - it'll make sense! hopefully..
