Typing

The basic typing is given HERE

Difference is in typing Chillaksharam.
Note that there are two keys marked as ZWJ and ZWNJ

ZWJ - Zero Width Joiner
This key is used to get Chillaksharas. First type the Vyanjana of the chillakshara followed by ് and then click on ZWJ key.
Use ന for ൻ, ല for ല്‍, ള for ൾ, ര for ർ, ണ for ൺ

ZWNJ - Zero Width Non Joiner
This key is used to prevent two letters from joining with each other.
eg: To get proper letters instead of സോഫ്റ്റ്വേര്‍ add ZWNJ before വ to get സോഫ്റ്റ്‌വേര്‍.
