There is a distracting sound emitted when no completion is available. Black Box should support turning off the sound.

Shows GNOME Terminal settings window. I tried to get it in English, but it's very stubborn. Anyway, in the Text tab the last header "Klang" means "Sound" and the checkbox "Terminalglocke" (terminal bell) was unchecked by me. For accessibility reasons it might make sense to have it enabled by default.
