Enable Braille support

Specifies if the Braille support with the screen reader should be enabled.

Possible values:

  • Auto: Enable and disable Braille support based on automatic device detection. (Default)

Click here to see how the automatic Braille support works:

  • If the screen reader is not running, plugging in a Braille device will also start the screen reader. If the device is removed again, the screen reader will also be stopped.

  • If the screen reader is already running when plugging in a Braille device, the screen reader will not be stopped whenever the device is removed again.

  • The detection also works for devices plugged in at boot time.

  • Enabled: Braille support is always enabled.

  • Disabled: Braille support is always disabled.


Disable speech in Braille mode
