Type of key Description
Alphanumeric keys Enter numbers and (special) characters in edit dialog boxes.

Sign key Changes the sign of a numeric parameter. In the case of an
alphanumeric parameter, inserts a "-" at the cursor position.
Unit keys

μ
V, M/
μ μ
V, k/m mV
and x1 dB(m))
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.
[INSERT] key Toggles between insert and overwrite mode
[ESC] key Closes all kinds of dialog boxes, if the edit mode is not active.
Quits the edit mode, if the edit mode is active. In dialog boxes
that contain a "Cancel" button it activates that button.

●

and closes the dialog box.
●
If data entry has not been started or has been completed, it
closes the dialog box.
[Backspace] key If an alphanumeric entry has already been started, this key dele-
tes the character to the left of the cursor.
