How to spellcheck tamil words in english version at once?

While posting contents under resources - entertainments - Tamil song & lyrics section the description box shows squiggly red line under the Tamil lyrics typed out in english version indicating spelling mistake. The spell checking and the grammar checking URL of TSR namely http://www.spellchecker.net/spellcheck/ and http://www.spellchecker.net/spellcheck/ is useful for correcting the english grammar but spell checking Tamil lyrics in English is to be done word by word. Is there any possibilities to select the whole typed in content, in the browser namely Internet explorer or Mozilla Firefox to "Add to dictionary" at once. I hope my query is understood.
