This is 'Direct Tamil Input' in MS-Excel. One can do this Tamil transliteration/typing in ANY windows application like MS-Word, MS-Powerpoint, MS-Access, Outlook Express, Wordpad, Notepad, Yahoo! Messenger, MSN Messenger, Yahoo! Mail, Hotmail etc. etc. For instance, start Azhagi fully, open any other application (say MS-Word), press 'F10', type in English and see it in Tamil. As simple as that.
