Malayalam Keyboard For PC ; Windows, Linux and Mac

      Malayalam keyboard for PC / Desktop is an On-screen Malayalam keyboard that built using java programming language and will work on Windows, Linux and Mac operating systems.

Malayalam Keyboard for PC

     In the Unicode character representation Malayalam characters are available in between 0D00–0D7F hexadecimal values. In this software you can find all the Malayalam characters as buttons in the application. Clicking on the button will display corresponding character on the screen.

Normally the Malayalam characters like ‘മ്മ’ is written using മ + ് + മ and ‘ക്ക‘’using ക + ് + ക. Ii this application, I have added a shortcut to this via Mouse Right Click. For example, the normal left click on the മ will give മ itself and right click on the മ will give മ്മ. This is applicable for all characters.

Left Click On ‘മ‘

Right Click On ‘മ്മ’

   The ‘BACK’ button will give the normal backspace effect and ‘SPACE’ will do the normal space. ‘SAVE’ can be used to copy the contents in textbox to memory/clipboard which then can be pasted to other applications.
