Overview

Dvorak keyboard layout

Dvorak Simplified Keyboard layout designed for efficiency:

• English (en, en-US) with Dvorak layout

Key differences from QWERTY:

• Vowels (AOEUIDHTNS) on home row left

• Most common consonants on home row right

• Designed to minimize finger movement

• ~70% of keystrokes on home row (vs ~32% for QWERTY)

Key positions use [row, col] coordinates where:

• row 0: number row (‘1“2>…)

• row 1: top row (‘,.<pyfg…)

• row 2: home row (aoeuidhtns…)

• row 3: bottom row (;qjkxbmwvz)
