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....

- Missed keys
- Not working key combos
- Not working macros
- Sometimes last typed key is repeated endlessly until I tap another key
This happens both on Bluetooth and USB. Example of not working key combo:- Select A (Cmd + A), defined in QMK as LGUI(KC_A)
- Works half of the time
Example of not working macro:- Missing keys is just during normal typing
- Repeating keys is often when multiple keys are pressed
- I defined a different layer in QMK with symbols like =_+-, those are not working at all. Which is strange, because they are send by QMK. The OS (and the BT-500) are agnostic about those layers.
All is working fine when directly connected to my Mac.
