Since yesterday, I am trying to submit a complete comment, but due to a 'Communication Breakdown' error, I am not able to submit it fully. Just the images are being uploaded. Sorry for that..!

Let me elaborate with a more simple example. The Marathi sentence below simply means : My name is Abhishek.

Devanagari : माझे नाव अभिषेक आहे.

Modi : 𑘦𑘰𑘖𑘹 𑘡𑘰𑘪 𑘀𑘥𑘱𑘬𑘹𑘎 𑘁𑘮𑘹.

IAST : mājhe nāva abhiṣeka āhe.

 

For typing 𑘦𑘰 in 𑘦𑘰𑘖𑘹, I used the key "M" + key "A" (𑘦 + 𑘰 = 𑘦𑘰). Similarly, for 𑘖𑘹, I used key "J" + key "E" ( 𑘖 + 𑘹 = 𑘖𑘹)

𑘡𑘰 : N + A (𑘡 + 𑘰 = 𑘡𑘰)

𑘪 : V

𑘀 : Alt + A

𑘥𑘱 : (Shift + B) + I (𑘥 + 𑘱 = 𑘥𑘱)

𑘬𑘹 : X + E (𑘬 + 𑘹 =𑘬𑘹)

𑘎 : K

𑘁 : Shift + A

𑘮𑘹 : H + E (𑘮 + 𑘹 = 𑘮𑘹)
