Thanks Rahul, that works.
However, on Ff 3, I was not able to enable and disable the transliteration bookmarklet as documented at:
http://t13n.googlecode.com/svn/trunk/blet/docs/help_mr.html#StoreFF. I was not able to see the devanagari अ character on the text field (text-area?) to enable/disable it. This makes it difficult to create a document that contains a transliterated text along with non-transliterated (as in verbatim) characters.
Regards,
Kedar
