plete the entry.
For 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.

and closes the dialog box.
●
If data entry has not been started or has been completed, it
closes the dialog box.

If an alphanumeric entry has already been started, this key dele-
tes the character to the left of the cursor.

"Hz/dB" unit key.
