Morton Jonuschat 7c0f2ae6d1 [Keymap] Neo2 for ErgoDox on MacOS US QWERTY / ABC Extended keymap (#5862) 
This is a Neo2 inspired layout that is meant to be fully usable on
MacOS when used with the default US QWERTY/ABC Extended keymap.

Neo2 layers 1-4 have been almost fully implemented in hardware.
Layers 5 and 6 (greek and mathematical symbols) have been left
out for now as most of them aren't available on the default
keymaps.

Layer toggling for layer 3 on the right hand side utilizes a
tap-toggle approach that is a combination of MO & LT macros.
This is required to allow sending Y when tapped, @ when tapped
while the SHIFT modifier is active and support momentarily
toggling the layer while the key is held.

Neo 2 for ErgoDox on QWERTY

Description

The Neo layout is an optimized German keyboard layout developed by the Neo Users Group, supporting many Latin-based alphabets. The positions of the letters are not only optimized for German letter frequency, but also for typical groups of two or three letters. English is considered a primary target as well.

The design tries to enforce the alternating usage of both hands to increase typing speed and incorporates ideas from de-ergo and other ergonomic layouts. High frequency keys are placed in the home row. The current layout Neo 2.0 has unique features making it suited for many target groups such as programmers, mathematicians, scientists or LaTeX authors.

Neo is grouped into six layers, each dedicated to a special purpose.

Layers

At the core this is a Neo 2.0 layout adjusted for the Ergodox Infinity. The keymap is laid out expecting a macOs using the US QWERTY or ABC Extended layout.

Layer 1 Lowercase, upppercase and typographical characters

Layer 2 Special characters for programming

Layer 3 WASD-like movement keys and number block

Layer 4 Greek characters

Layer 5 Mathematical symbols and Greek uppercase characters

Layer 6 Ergodox Infinity US QWERTY layout

Layer 7 Function keys

Legend

  • Keys marked with ---- are dead keys.
  • Blank keys are transparent and fall through to lower levels.

Layer 1

This layer implements NEO layers 1 and 2.
