Unit keys
These keys add the selected unit to the entered numeric value and complete the
entry. In the case of level entries (e.g. in dB) or dimensionless values, all units have
the value "1" as multiplying factor. Thus, they have the same function as an
[ENTER] key. The same is true for an alphanumeric entry.
