Hey Guys,
I thought I will double post on the Grantha keyboard stuff.
I have modified the NHM Bengali phonetic XML file to make it suitable for the e-Grantamil Grantha.
Right click the XML file and save it your local disk, and then Install the keyboard in NHM Writer.
Let me know if any suggestions, improvements and of course bugs on the keyboard.
Make sure, the font is set to "e-Grantamil" before attempting to use the keyboard. Else you will be struck up composing Bengali Text :-P
If you face any difficulties in installing/using the keyboard post in this thread.
Thanks !
