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....

Those keys are all normally 1.25U. Corsair CTRL is 1.5u, windows/fn/menu are 1u.
The 18 macro keys on the K95/RGB use a slightly smaller keycap size, no normal keycaps will fit it. The switches are slightly too close so caps will hit adjacent keys. I used a K95 previously.
Also, I've already stated there isn't any support for the Macro cluster regardless of the old K95(18Gkeys) or the new K95 Platinum.
@fairlane1966 It's 100% guaranteed the K95 bottom row is supported and all the other Corsair mechanical keyboard's bottom row, except the space bar as mentioned. The 'Code' can replace the 'Menu' key if you're not aware. Corsair's Full-size keyboards don't contain a physical mech 'Fn' switch; it's replaced with the standard 'Menu' key. Only on TKL models and below will have 'Fn'.
