BrailleExtender is a NVDA add-on that provides various features at braille level. Currently, the following features are implemented:

Besides, for some braille displays, it extends the mapping:

Once the add-on is installed, I suggest you read the documentation and go through the settings using the BrailleExtender menu (located at the root of NVDA menu).

This add-on is still in development, there are some bugs, the documentation needs to be improved and other features are coming.

Any comments, bugs, suggestions are welcome.
