Keys Description
0...9/abc Enters the corresponding numbers (in numeric input fields) or characters (character input
fields).
. Inserts a decimal point (numeric input fields) or dot (character input fields) at the cursor posi-
tion. Multiple decimal points are not allowed.
+/- Changes the sign of a numeric parameter. In the case of an alphanumeric parameter, inserts
a hyphen at the cursor position.
Unit keys Selects a unit and thus determine the absolute value, or changes the unit, i.e. trigger a recal-
culation without changing the absolute value. The function depends on the time at which the
UNIT key is used during parameter entry (see
​
chapter 4.4.5, "Working with Units
" , on page 80).
For unit-free values, the X1 key is equivalent to ENTER. It confirms the previous entry and
deactivates the input field.
_ Adds a blank in a character input field.
*... # Enters special characters. Toggles through the available characters if the key is pressed sev-
eral times in a row.
A <-> a Toggles between uppercase and lowercase characters.
A, B, C, D, E,
F Enters hexadecimal values. The letters assigned to the keys are automatically active when
an entry field with a hexadecimal value is active.
INSERT
Toggles between insert and overwrite mode (see also
​
chapter 4.4.4, "Entering a
Value" , on page 79 ).
