What is the InScript Keyboard Standard?
InScript (short for Indic Script Keyboard) is the official standard keyboard layout designed by the Centre for Development of Advanced Computing (CDAC) and standardized by the Bureau of Indian Standards (BIS) in 1986.
The primary innovation of InScript is its universal phonological architecture. Because all major Indian scripts share a common phonetic origin, InScript places corresponding phonetic sounds on identical physical QWERTY key locations across all 12 major Indian languages (Tamil, Hindi, Devanagari, Telugu, Kannada, Malayalam, Bengali, Gujarati, Punjabi, Odia, Assamese, and Marathi).
InScript Key Layout & Finger Distribution
InScript categorizes keys into distinct hand zones across standard QWERTY physical keycaps:
- Left Hand Keys = Vowels & Matras (உயிரெழுத்துக்கள் & குறியீடுகள்): Left-side keys handle vowels (அ, ஆ, இ, ஈ...) and their corresponding diacritic matras.
- Right Hand Keys = Consonants (மெய்யெழுத்துக்கள்): Right-side keys handle primary consonants (க, ங, ச, ஞ, த, ந, ப, ம...).
- Shift Key Layer: Unshifted keys represent short vowels and unvoiced consonants, while Shift keys access long vowels and aspirate sound variations.
- Halant / Virama Key (D Key): Pressing D inserts the dot (Pulli / புள்ளி) on consonants to create pure consonants (க், ங், ச்...).
InScript vs. Tamil 99 vs. Phonetic Comparison
| Comparison Dimension | InScript Standard | Tamil 99 Standard | Phonetic (E2T) |
