4.2.1.3 Data Entry Keys
The keys in the DATA ENTRY keypad are used to enter numbers, units, and charac-
ters. The data entry keys are only enabled while the cursor is placed on a data input
field in a dialog or in the Help navigation pane.
●
The keys 0 to 9 enter the corresponding numbers.
●
The function of the "." and "–" keys depends on the data type of the active input
field:
– In numeric input fields, the keys enter the decimal point and a negative sign for
the entered numeric value. Multiple entries have not effect.
– In character input fields, the keys enter a dot and a hyphen, respectively. Both
entries can be repeated as often as desired.
●
The function of the four unit keys depends on the data type of the active input field;
see Chapter 4.3.5, "Entering Data", on page 63.
– In numeric input fields, the G/n, M/μ, k/m or x1 keys multiply the entered value
with factors of 10

or 1 and add the appropriate physical unit. x1
is equivalent to ENTER and confirms the previous entry.
– In character input fields, the G/n, M/μ, k/m keys enter the letters G, M, K,
respectively. x1 is equivalent to ENTER and confirms the previous entry.
●
ESC is used to:
– Cancel entries / close dialogs without activating the entries made (equivalent to
the "Close" button).
– Close the Help system.
●
ENTER is used to:
– Activate the selected active control element, e.g. a button in a dialog or a link in
the "Contents" page of the Help system.
