TheAmarin's Neo2-based Layout
================================
This layout is based on [Neo2](https://www.neo-layout.org/), an ergonomic keyboard layout optimized for coding and German language.
**neo2marin** tries to squeeze Neo2 onto the Planck keyboard.
Neo2 already uses several layers with multiple modifiers, so we don't have to invent new layers.
A major difficulty is the missing 'hashtag' key which is usually left to the 'return' key on German QWERTZ keyboards.
Another astonishing thing might be that `return`/`enter` needs a modifier (`MOD4`+`P`).
This layout makes heavy use of the split `space` key, as its left part becomes the quite important `MOD4` modifier.
## The Neo2 Main Layer
```
|----+----+----+----+----+----| |----+----+----+----+----+------|
|TAB | X | V | L | C | W | | K | H | G | F | Q | SS |
|----+----+----+----+----+----| |----+----+----+----+----+------|
|MOD3| U | I | A | E | O | | S | N | R | T | D |Y/MOD3|
|----+----+----+----+----+----| |----+----+----+----+----+------|
|LSFT| Ü | Ö | Ä | P | Z | | B | M | , | . | J |RSFT |
|----+----+----+----+----+----| |----+----+----+----+----+------|
|LCTL|LGUI|LALT|SWAP|MOD5|MOD4| |SPC |SWAP|MOD5|APP |RALT|RCTL |
|----+----+----+----+----+----| |----+----+----+----+----+------|
```
Unfortunately, `y` and `MOD3` (switch to layer 3) need to share a single key.
This works for me most of the time but I am happy [to learn about your solution](https://github.com/theamarin/qmk_firmware/issues)!
## The QWERTZ fallback layer
I nearly never use this layer, so there may be room for optimization.
```
|----+----+----+----+----+----| |----+----+----+----+----+------|
|TAB | Q | W | E | R | T | | Z | U | I | O | P | Ü |
|----+----+----+----+----+----| |----+----+----+----+----+------|
|CAPS| A | S | D | F | G | | H | J | K | L | Ö |Ä/MOD3|
|----+----+----+----+----+----| |----+----+----+----+----+------|
|LSFT| Y | X | C | V | B | | N | M | , | . | SS |RSFT |
|----+----+----+----+----+----| |----+----+----+----+----+------|
|LCTL|LGUI|LALT|SWAP|MOD5|MOD4| |SPC |SWAP|RALT|APP |RALT|RCTL |
|----+----+----+----+----+----| |----+----+----+----+----+------|
```
The German `ß` has moved right to the `.` key, and we have to reuse `Ä` for `MOD3` again.
## MOD3: The Coding Layer
This is definitively the coolest part of Neo2, having most of the coding-related symbols right on your home row!
Of course, this is the only way to do it on Planck.
```
|----+----+----+----+----+----| |----+----+----+----+----+----|
|' | € | _ | [ | ] | ^ | | ! | < | > | = | & | ` |
|----+----+----+----+----+----| |----+----+----+----+----+----|
|MOD3, \ | / | { | } | * | | ? | ( | ) | - | : | @ |
|----+----+----+----+----+----| |----+----+----+----+----+----|
|LSFT, # | $ | | | ~ | ' | | + | % | " | ' | ; |RSFT|
|----+----+----+----+----+----| |----+----+----+----+----+----|
|LCTL|LGUI|LALT|SWAP|MOD5|MOD4| |SPC |SWAP|MOD5|APP |RALT|RCTL|
|----+----+----+----+----+----| |----+----+----+----+----+----|
```
Because `y` and `MOD3` have to share a key, we need two variants of the MOD3 layer (as can be seen in the keymap).
## MOD4: The Movements Layer
```
|----+----+----+----+----+----| |----+----+----+----+----+----|
| |PGUP|BSPC| UP |DEL |PGDN| | | 7 | 8 | 9 | + | - |
|----+----+----+----+----+----| |----+----+----+----+----+----|
| |HOME|LEFT|DOWN|RGHT|END | | | 4 | 5 | 6 | , | . |
|----+----+----+----+----+----| |----+----+----+----+----+----|
| |ESC |TAB |INS |ENTR| | | 0 | 1 | 2 | 3 | ; | |
|----+----+----+----+----+----| |----+----+----+----+----+----|
| | | | | | | | | 0 | | | | |
|----+----+----+----+----+----| |----+----+----+----+----+----|
```
## MOD5: The Fun(ctions) Layer
```
|----+----+----+----+----+----| |----+----+----+----+----+----|
| |AUD1|VOLD|MAXM|VOLU| | |M1R | F7 | F8 | F9 |F12 |PSCR|
|----+----+----+----+----+----| |----+----+----+----+----+----|
| |MSTP|MPRV|MPLY|MNXT|NEO2| |M1S | F4 | F5 | F6 |F11 |BRK |
|----+----+----+----+----+----| |----+----+----+----+----+----|
| |AUD0|TAB |INS |ENTR|QWERTZ |M1P | F1 | F2 | F3 |F10 | |
|----+----+----+----+----+----| |----+----+----+----+----+----|
| | | | | | | | | | | | | |
|----+----+----+----+----+----| |----+----+----+----+----+----|
```
Have fun!
