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....

RGB is all presets. For solid colors, your options are red, green, blue, yellow, purple (lavender), cyan, and white, and none (off). Everything else -as far as I can tell- is just some kind of typical rainbow effect. I am very happy with just being able to set it to white. There are 5 brightness levels, and the LEDs are as bright as the DREVO Gramr 84, and much brighter than its predecessor: the Keycool Hero 84.
The build quality is just as good as the original Keycool Hero 84, which makes it leagues better than the DREVO Gramr 84. Just like the original, the housing is solid plastic with a metal plate on the inside for weight. In contrast, the Gramr 84 chassis can be flexed in your hands and weighs less, though this shouldn't really affect normal operation...
The cable is detachable mini-usb, and comes with a transparent plastic bracket that can be inserted onto the plug body for security; it basically prevents damage from yanking on the cable.
I can't particularly tell the difference between the Gaterons and Cherry MX, so I see no problem. The included keycaps give it a hollow sound when bottoming out, but I will be replacing those with shine-through keycaps from Aliexpress.
I'm very happy with it, I think I'll buy another.
EDIT: Found out one more thing. The original Keycool Hero 84 and similar keyboards like the Noppoo Choc Mini had a numpad mapped as function keys under 789. It was a terrible numpad and we all hated it. Unfortunately, if you wanted to use a standalone numpad on the side, numlock on the external one would cause the functional numpad on the board to activate, so you couldn't use a standalone numpad with the Keycool Hero 84. The Keycool Hero 2S fixes this problem by completely removing the numpad feature. Thank. God.
Could you share the important keymaps to know ? Such as switching RGB presets, etc...
EDIT : Or at least somewhere where I can find the bindings haha
-Fn+\| or Fn+Pause -Fn+Esc until it turns solid red -Fn+Home to change color
I will post some pictures when I get home.
