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....

Still in feedback/design phase. Hasn't moved onto a proper IC (which i believe will be on geekhack)
I now wonder if somebody with the Jukebox keyset will make a jukebox-ish case :)
Though my favourite keyset is probably still the symbiosis keyset (I like the math symbols) [2] http://keypuller.com/symbiosis/ Perhaps at some point I should make my own math-inspired keyset, I could base some of it off an APL keyboard---that way it will essentially be a fancy blank keyset, for natural language typing anyway.

Oh well, it's my own fault
