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....

A note about red LED keyboards. I bought blue and white color changers, they do nothing. The light is just a fainter red.
I have a K70 Blue with red LEDs.

If you put a blue film over a red light, no light will be let through (or minimal light). A blue film lets blue light through, and a red light doesn't project any blue light, therefore no (or minimal) light will be let through. Similarily, a green film will let green light through, but hardly any light from a pure blue or a pure red light source. As well as a red film will let much less light through from green and blue sources. A white film will reduce light from all 3 primary colours (red, green, blue), simply making any LED slightly darker.
