When a visual keyboard is the right tool
Phonetic typing is faster once you know Avro spellings. Until then, many people hunt for a single letter — য়, ৎ, ং, ৃ — and give up. An on-screen keyboard is slower, but it is honest: you see every independent vowel, consonant and kar.
This layout follows the usual Bangla alphabet order, not a QWERTY map. That is deliberate. Bijoy operators already have muscle memory for a different physical keyboard. Beginners who only need a name, an address or a school heading should not be forced to learn that map for five minutes of typing.
After you finish, the text is Unicode. Paste it into Word, a form, or the Bijoy converter if the next person in the chain still uses SutonnyMJ. Combine this keyboard with the word counter if you have a character limit.
When this does not apply
Long essays belong on Avro phonetic or a real IME. This layout is not Bijoy key positions — operators who already know that map should not relearn the alphabet order here.
