The answer sound of the key touch is too loud, I would like to add a feature to reduce or turn it off.

Go to main/hal/hal_cardputer.h and change these values in the follow lines:

void playKeyboardSound() override { _speaker->setVolume(72); _speaker->tone(5000, 20); }
void playLastSound() override { _speaker->setVolume(32); _speaker->tone(6000, 20); }
void playNextSound() override { _speaker->setVolume(64); _speaker->tone(7000, 20); }
