Hoi,
The Narayam extension was developed to support keyboard methods. It was first developed for the Malayalam language as a script that was running locally and then as Junaid PV became a MediaWiki developer, it and the support for other languages was included in this extension.

I blogged today about the relevance of this functionality and I asked Raon, one of the MediaWiki developers, if he is happy to bring it into production and finally I asked the good people at translatewiki.net to support its localisation.

So this is the situation:
As I know it, this is the first software contribution coming from the Indian communities and, I could not be more pleased with it. Please help by helping yourself and yes, we would like to see more Indian MediaWiki developers :)
Thanks,
