Show HN: Neolight – Extra keyboard layer with special characters for programming

I created this about 7 years ago, after using Neo for a year (a custom keyboard layout optimized for German) and finding that having messed up shortcuts in games and other applications was not worth it for me. Also readjusting to qwertz when typing on somebody else's computer always took a while.

My goal was:

* to create a layout that has the extra layers useful for programming from Neo, but otherwise be standard qwertz as much as possible

* while being usable in combination with any layout (not just German), provided the keyboard has the right set of keys for the modifiers
