The Tûbu soft keyboard allows typing in Teda/Tudaga and Goran/Dazaga as well as in English and French.
Teda/Tudaga and Goran/Dazaga are Saharan languages spoken in the central Sahara.

To use this keyboard you have to configure it in the settings „Language and Input“: Activate the keyboard „Ollo Arba Tûbu (Tudaga yê Dazaga yê)“; then set it as your default keyboard.

This is still a preliminary version, but can be fully used.
