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. My SpaceFN article on kbd.news made some rounds recently - quite surprisingly given the age of this concept. This piece you're reading is a condensed version of the full post. 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? In short: SpaceFN is easy to implement, easy to learn, costs nothing, can be used with any keyboard, and can improve your productivity instantly. I will list its benefits below, but can state right at this point that the SpaceFN concept, setting up your space key as a layer switch when held, is clearly one of the most useful tweaks in the keyboard hobby....

I know >.< this much about keyboard electronics but if makers out there could come together with a standard chipset they all agreed to use then a cross platform app should be pretty easy to put together.
I know ... less hacker ... more hipster ... but the more people you get on board the more diverse styles of keysets you will see for this; again IMHO.
But yeah, these are definitely options, and I'm hoping to build a web-based one soon!
Though for keyboard/mouse mapping Easy AVR is pretty complete, and the author continues to add features.
