This is the "Transparent" mode of Transliteration in Azhagi.
The top text area is the 'English Text Area' where
user types his english text. The bottom text area is the
'Tamil Text Area' where the equivalent tamil text appears.
The transliteration is synchronously done.
Its possible to generate mixed text (i.e both English and Tamil) also using Azhagi, which is what the above snapshot depicts.
