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.

This one is silent, but it's from a third party seller and not from amazon, so you can't buy it outside japan. :-( I think the model number is SE170S for black and SE070S for white, if you want to try looking for it somewhere else.
