Optical Key Code
. The presence of a finger blocking the optical barrier
will generate an event equivalent to a

although we recommend comparing finger presence to the pressing of the green key.
For this reason, the default value is 0x41 (corresponding to ‘A’).
Permitted values:
- 0x00 .. 0xFF: Any, although we recommend an alphanumerical value.
