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....

The home and QWERTY rows (not sure how to count rows on this profile; rows 3 and 4?) have really deep dishing, more than any keyboard I've used since the Commodore 64 -- its spherical profile is frankly my touchstone (although literally their switch mechanism was terrible) since I learned to type on it. But those two rows are noticeably deeper than the other rows, which begs the question of consistency. It feels like those rows are all homing-dished... It's distracting now but hopefully that distraction would go away with use, so I'll have to wait and see, but since the other rows are less dished I'm pretty sure it's always going to be an issue.
The feel of the plastic itself is top notch, velvety textured, and the keys arrived spotless and without a scratch, foam-protected or individually bagged (!) and the profile (while problematic for some non-standard key layouts) is amazing and pairs well with a modest slant to the keyboard. I initially put them on an XD75 with a 5 or 6 degree slant and it's perfect. I like that the FN key row is still sculpted, and also I hate it because I can't use any of that row custom keys I ordered yet! I'll need to get a TKL or something...
The sets have enough alternates to do some odd boards like XD75 and Planck but not necessarily the keys you want in the profile row you want. You may also find the dishing a bit hard on the thumbs for the 2U or 1U spacebars; I had two alpha kits and used the extra ZXCVB-row 1U blanks that are included in that set, mounted upside down, to let my thumbs more naturally rest; they are really good for this application! I was kind of surprised that nothing I ordered (alphas, mods, ortho, extra mods, and novelties) included a home-row CTRL key at 1U or any 1U BS... but I think people have already discussed the ortho set limitations. Anyway, there was considerably variety available though having way more "END" keys than "HOME" made me scratch my head a bit until I realized some layouts stick other keys between them vertically. BTW, I didn't even try to order this set for Ergodox since when I ordered the large blanks weren't part of the drop and by the time I noticed they were added it had ended. I would have ended up with about as many extra kits and as many keys I'm not able to use. I have a LOT of END keys btw.
Here's a real bummer: the printing, while consistent in tone and durability, is otherwise... subpar. Many of the legends are slightly off center, many moved slightly to the right. The fuzziness of the legends is a bit more noticeable than in other sets I have and makes the number+symbol keys look out of character with the rest. Even the /dev/tty novelty key is muddy and hard to read. My W and K keys are just slightly rotated from level and some keys have slightly lower baselines. Whatever printing system was used was not registering the key locations well enough. It's a tragedy because otherwise they are just amazing, and I hope the next drop will be able to rectify this.
The Extras set has a really nice orange WASD/arrows accent that reminds me of orange sherbet, and I kind of wish I had more of that (but then this isn't Carbon!). The dark blue used for the /dev/tty novelty branding key is too dark for the black legends but a nice blue. Ortho kit's RSE and LWR come in both the grey and orange/light blue that Plancks like, in a flat profile designed to be used on the spacebar row. Again I find the spacebar row slightly uncomfortable to hit with my thumb, but your milage may vary.
