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....

More time on a machine means someone to set up the machine, someone's being paid while the machine is running even if they're not manually controlling the machine, so there is a cost increase. You factor in more time on the machine is more wear on the tools, cost increase factored in. More time making one part means less time to make other parts, so your production speed goes down and cost per part goes up. You can't just turn up the speed and cut faster as machining has max cutting speeds all based on material type, material of the tool, radius of the tool, feed rate of the tool, how cool you keep the tool. machine that's doing the work, etc.
Then the base of the case has an angled cut built into it. That requires either the machine to angle the part, an operator to set the part manually or use a jig that needs to be built for this project and requires extra money. The design of the CTRL and ALT by themselves were very basic. This has a lot more going on with it.
