[Blindmath] Is there any open source program for editing braille?

[Saaqib Mahmuud]

Hi Blind Math mates? How's it going? 

My query though not directly on mathematics can be beneficial to many people. 

Is there any open source software program that can perform similar functionality as the Duxbury's DBT program? I mean is there any program that can enable editing of braille using the f-d-s-j-k-l keys on the computer keyboard? 

Regards.
