How to use Senthamizh Font

How to use keyman for sentamizh font. please guide me…

Hi John. Welcome to the community.

I’m not clear on what you are asking. We do have quite a few Keyman keyboards for Tamil if that is what you are looking for. You can look here to find one suitable:
https://keyman.com/keyboards/h/tamil/

Most of the keyboards have a help page where you can look at the keyboard layout (before downloading and installing the keyboard) to see if it is a layout that would be what you need.

If you are looking for a specific font, I believe you will need to do a Google search for that. I’m not familiar with a font by that name.

It is not a keyboard layout that has been added to the Keyman repository. I only found one blog post on it, and my guess is it’s a privately distributed installer using an old version of Keyman. You may want to try contacting the develi.
