This #Wiktionary screen shot shows the first iteration of the language support that will be brought to MediaWiki by the Wikimedia Localisation team. It makes it possible for people with a standard US keyboard to emulate a keyboard appropriate for their language.
Narayam, the MediaWiki extension, was originally conceived by JunaidPV and has been further developed to provide keyboards for many more languages. Particularly the people who use the languages from India will benefit. Many different scripts are in use but many computers do not have an appropriate keyboard for the many different languages.
Now that Narayam is live on some wikis, we will gain the experience necessary before it will go live on other projects and for other languages. When it works well, external tools like the ones shown on the Sanskrit Wiktionary can be phased out as well.
At translatewiki.net you will find keyboard methods for many more languages. Please try them out and, when you cannot find a keyboard method for your language, you may discuss within your community if Narayam can be beneficial for your language.
