Systems, devices, and methods described herein provide an input device having keys operatively coupled with light devices that emit light out of the keys. The input device is associated with different modes of operation. The light devices emit the light out of the keys responsive to a selected mode of operation being a first mode of operation. The light devices stop emitting the light out of the keys responsive to the selected mode of operation being a different, second mode of operation. The light devices are activated to indicate the selected mode of operation. One or more processors perform first functions associated with the keys during the first mode of operation and perform different, second functions associated with the same keys during the second mode of operation.
