Implement core keyboard layout conversion supporting Korean, Russian, Arabic, Hebrew, German, Spanish, Czech, Greek, Persian, Belarusian, Ukrainian, Kazakh (via convert-layout), plus Japanese (wanakana), Chinese (pinyin), and Hindi (sanscript) with specialized converters.

- Create keyboard-layout-converter.ts with layout conversion logic
- Add comprehensive unit tests covering all 15 languages
- Add TypeScript type definitions for external dependencies
- Install required dependencies: convert-layout, wanakana, pinyin, @indic-transliteration/sanscript

 - ⚡ **Instant Access**: Click any button to run terminal commands or VS Code functions
 - 🎨 **Color-Coded**: Distinguish different command types with custom colors
 - 📱 **Smart Terminals**: Each command gets its own named terminal session
+- ⌨️ **Multi-Language Keyboard Shortcuts**: Use shortcuts in your native keyboard layout - Korean `ㅅ` automatically maps to English `t`, Japanese `あ` to `a`, etc. Supports 15 languages including Korean, Japanese, Chinese, Hindi, Russian, Arabic, and more

 - **`Ctrl+Shift+;`** - Open command palette
 - **Single keys** - Quick command execution in groups (e.g., press `g` then `s` for Git Status)
 
+### Multi-Language Keyboard Support
+
+- **🌐 Global Compatibility** - Works seamlessly with 15 keyboard layouts and input methods: Korean, Russian, Arabic, Hebrew, German, Spanish, Czech, Greek, Persian, Belarusian, Ukrainian, Kazakh, Japanese, Chinese, and Hindi
+- **🔄 Auto-Translation** - Shortcuts automatically map between keyboard layouts and transliteration systems
+- **⌨️ Natural Typing** - Use your native keyboard layout without switching to English
+- **🎯 Smart Matching** - Type `ㅂ` on Korean keyboard to trigger `q` shortcuts, or `あ` in Japanese to match romaji equivalents
+- **🇯🇵 Japanese Support** - Hiragana, Katakana, and Romaji conversion using WanaKana library
+- **🇨🇳 Chinese Support** - Traditional and Simplified Chinese with Pinyin conversion
+- **🇮🇳 Hindi Support** - Devanagari script with IAST transliteration support
+
 ### Pro Tips
 
 - Use `$(icon-name)` syntax for VS Code icons in button names
 - Group related commands to keep status bar clean
 - Use `executeAll: true` for monitoring multiple processes
 - Mix terminal commands with VS Code API calls seamlessly
+- Type shortcuts in your native keyboard layout - no need to switch to English!
