What is SpaceFN and why you should give it a try
The SpaceFN concept - setting up your space key as a layer switch when held - is probably one of the most useful tweaks in the keyboard hobby. Let me explain how it works.

If you're left with unanswered questions, you'll most likely find the info you're looking for in the original write-up. On my imaginary top list of the most useful keyboard features, tweaks and hacks, SpaceFN would deserve a podium finish for sure. But what makes it so special?

My take is that the Extra Modifiers are created so that 40% boards only need Alpha + Extra Mod and by pass the Basic Mod. But would be nice if someone can confirm or point out what's needed in the Extra Modifiers.
