Overview

JCUKEN keyboard layout

Standard JCUKEN layout used for:

• Russian (ru, ru-RU)
• Ukrainian (uk)
• Belarusian (be)
• Bulgarian (bg)

This is the standard Cyrillic keyboard layout. Key differences from QWERTY:

• Completely different alphabet (Cyrillic: 33 letters)
• JCUKEN mapping corresponds to QWERTY positions
• Has special keys: ё, ъ, ь

Key positions use [row, col] coordinates where:

• row 0: number row (ё1"2...)
• row 1: top row (йцукен...)
• row 2: home row (фывап...)
• row 3: bottom row (ячсми...)
