# Attic Greek (ABNT2)

A polytonic Ancient (Attic) Greek keyboard layout for Brazilian ABNT2 keyboards, built with [Keyman Developer](https://keyman.com/developer).

##

## Overview

This keyboard allows typing polytonic Attic Greek — including breathings (smooth/rough), accents (acute, grave, circumflex), vowel quantity marks (macron/breve), iota subscript, and dialytika — directly from a standard Brazilian ABNT2 physical keyboard, without needing to remap the underlying OS layout.

It is intended for students and researchers of Ancient Greek philology, philosophy, and classics who work on ABNT2 hardware and want an intuitive, discoverable set of deadkey combinations rather than memorizing raw Unicode code points.


## Features

* Full polytonic coverage: smooth (᾿) and rough (῾) breathings, acute, grave, and circumflex accents, iota subscript, and dialytika

* Macron/breve (vowel quantity) combinations for α, ι, υ

* Deadkey-based input: compose diacritics onto a base vowel in any order supported by the ruleset

* On-Screen Keyboard (OSK) layout for visual reference on touch/desktop

##

## Installation

1. Download and install [Keyman](https://keyman.com) for your platform.

2. Install the `attic\_greek\_abnt2.kmp` package.

3. Select "Attic Greek (ABNT2)" from your Keyman keyboard list.

##

## Usage

Deadkeys are typed before or after the base vowel (see table below) to compose the desired combination. Refer to the on-screen keyboard (OSK) for the full deadkey map.

## Known limitations

* Macron/breve combinations are currently restricted to α, ι, υ.
