The keyboard includes a light emitter at each key for illuminating its associated key, and an electronic circuit is coupled to the switches and receives correct key location signals from the sensors detecting the code bars to activate correct and incorrect readout counters to indicate the number of correct and incorrect key activations and to activate the light emitter at the correct key location when a key at an incorrect location is activated.
