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....

Hydrographics are not bonded to the physical key but a set of layers on the key and then covered with a film generally that has an activator that bonds to the keys and then a coating is applied to the final layer so you end up with 3 layers of material, bond, print, coat. In this case the key does not physically have the print like dye sublimation which means the clear coating quality and the chemical used to bond are what control quality.
You are probably also thinking of hydro dipping in regards to quality which is a similar process that is far less professional (think paint and water with dipping/pulling). This is more professional and creates high quality results. Used on helmets, auto parts, and anything 'decorative'.
Hydrographic printing is not necessarily less quality than dye sub - only when the materials used in the process are of low quality. Both produce a result that will last depending on your usage and quality of the materials. Difficult thing is that as a consumer you will have no insight until you receive the final product.
