[laptop-accessibility] keyboard for the blind

[Manusheel Gupta]

Thanks to all for your help till date.

We have got pretty consistent feedback about the sufficiency of the standard
dots on "f" and "j" keys on the Braille keyboard. We agree that the dots
should be made larger, and are trying to investigate the range of size of
dots to reach the comfort zone for the children.

Any pointers at this end will be highly appreciated.

Thanks for your wonderful support.

Regards,
Manu
