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....

It sure made the flimsy plastic/wire filco one it replaced look like a toy and pretty much makes those cheapo rigid all plastic keycap pullers look like it came out of a happy meal.
Not once has it flinched pulling a cherry keycap (which I expect these will mostly see) or topre. It just laughs at the legendarily tight and stubburn ALPS switch keycaps and makes pulling model m buckling spring keys a walk in the park.
I got my first and shortly following, second one, from geekhack groupbuys and I might just get a third here. EDIT: haha a 3rd one never hurt! I'm in!
If you're concerned about the longevity of them, I've had mine for about over a year around my rotation of keyboards and going through 4 separate model m bolt mods and it's remained working as well and physically appearing as I got it on day one.
Here's a pic of my trusty workhorse with some spacesaver love for you guys:
