# bredfield's 4x12 Ortho Keymap

## Overview
This is the layout that I use for all 4x12 boards, for writing and programming.

- Works with planck or split style boards
- Split spacebar; left position is backspace, which frees up the typical key for minus/undersc
- Targets mac os; linux variant to come
- Navigation layer is triggered via the `;` key, allowing for single-hand navigation without leaving the home row
- Brackets are located on the home row on raise, which is comfortable when programming
- Reduced mod / layer tap use, to avoid input lag
- LEDs are overrated
