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....

I have a K95 Platinum with Cherry Browns, but I'm a bit disappointed by the inconsistency of the switches.
Though I'm a bit worried about opening this board. The K70 has a hidden screw under the company logo which is just glued on, so it can be wedged off. The K95 Platinum has an RGB logo in the same location, with the light bar right next to it. I'll try to find out if that needs to be removed, but I really don't want to damage it.
I think the best solution might be to pop the tops off the switches, lube them and replace any bad springs or sliders. I think all Cherry MXs share the same case, so with a bit of luck I might even be able to change them into Blues or Clears without opening the board.
Naturally I'll practice on something less expensive first. :)
I have made a hobby of collecting switch testers, so I have a large variety to choose from. The Zealios are a good option - they're noticeably smoother than Cherries or clones.
I will be sure to practice desoldering, resoldering and lubing on one of the secondhand keyboards I have, before doing it for real.
