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....

#7: Pressing FN+up/down changes the brightness level. #8: Pressing FN+left/right, I don't really know. I saw the tester press those keys in the video linked previously, but it was sped up so much that I couldn't exactly tell the effect. My inclination is that it changes the lighting effect speed though. Clarification or confirmation on this from someone would be appreciated though.
Edit: Yeah, functions should be the same as that keyboard. I just noticed that the description states "This keyboard sports the same basic set-up and core features of the Keycool 104 RGB."
