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....

- Find a very flat surface. I used an unused glass shelf from an old fridge.
- Fold a sheet of paper so it's about 1.5" wide and four layers thick.
- Run a hot hair drier over the spacebar for about 5 minutes. It will want to fly around so just surround it with a few books to keep it in place.
- Quickly, place the spacebar over the paper so it's centered and about 1.5" of each end are now hovering over the surface.
- Stack many heavy books onto the spacebar.
- Wait 15 minutes.
So the idea is that the paper in the middle will cause the ends to bend down more under weight. On my first attempt, I had tried it without the paper and it didn't help. I also put on rubber o-rings just on the spacebar to keep it from being inserted too deep into the stems. At first it would still stick if I press it down all the way but after pressing on it a few more times, something equalized and it's ok now.
