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....

Figure out the size of your space bar and the keys R1 keys immediately to the side (FN, CTRL, Win, etc.) and everything else should be a standard fit.
If the exact sizing isn't listed on a keycap product page, just check the bottom row: every fullsize is almost identical except for the bottom row, and maybe ANSI/ISO (https://deskthority.net/wiki/ANSI_vs_ISO) I believe Razer only makes ANSI? But this set should fit both. :)
Good luck with your customization, and good luck to your wallet lol
