# ErgoDox EZ Code Friendly Qwerty Layout
- This layout aims to balance muscle memory from a typical QWERTY layout
with having keys used for software development easily accessible.
- Arrow keys follow VIM convention (the media layer even uses arrow keys for HJKL).
- On the top row only symbols are used (not numbers),
it's expected the symbol layer's number-pad layout will be used for numbers.
- Symbols match regular QWERTY.
except for '()' which are grouped with other brackets.
In their place -/= keys are placed, which almost matches a regular layout.
- Brackets are placed symmetrically along the center edges,
if using keys from both sides is inconvenient - the symbol layer has macros
at the same key locations to type matching pairs.
- The extra space-bar on the lower-left looks like it's in an obscure location,
however using the larger thumb cluster ended up being more of a reach while typing.
- L3 is currently only used if `CFQ_USE_EXPEREMENTAL_LAYER` is defined,
this is a layer to place extra functionality and test new keys.
## Configuration
Some optional behavior is configurable without editing the code
using `CFQ_` prefixed defines which can be set by passing `EXTRAFLAGS` to make.
- `CFQ_USER_KEY1` (1..4) are used for custom-keys
- `CFQ_USE_MOMENTARY_LAYER_KEYS` is used to prevent layer keys from toggling when tapped.
- `CFQ_USE_SWAP_RIGHT_SPACE_ENTER` swap Enter and Space on the right hand thumb cluster.
While asymmetric, it makes Enter more easily accessible.
- `CFQ_USE_EXPEREMENTAL_LAYER` defines an extra layer for misc extra keys/macros.
Currently it's mostly empty.
## Keymap 0: Basic layer
When undefined:
- `USR1` defaults to `KC_SPC`, otherwise use `CFQ_USER_KEY1`.
- `USR2` defaults to `KC_ENT`, otherwise use `CFQ_USER_KEY2`.
- `USR3` defaults to `KC_FN3`, otherwise use `CFQ_USER_KEY3`.
- `USR4` defaults to `APP`, otherwise use `CFQ_USER_KEY4`.

## Keymap 1: Symbol layer
Notes:
- The double bracket keys on this layer press left to position the cursor between them.
- The left thumb cluster is used for macro record/replay.
