2.1.5 Data Entry Keys
The keys in the data entry keypad are used to enter numbers and units.
Data entry keys are only enabled while the cursor is placed on a data input field in a
dialog. Their function depends on the data type of the input field.
The keys 0 to 9 enter the corresponding numbers (in numeric input fields) or characters
(character input fields).
●
In numeric input fields, the keys enter the decimal point and change the sign of the
entered numeric value. Multiple decimal points are not allowed. Pressing plus/minus
for a second time cancels the effect of the first entry.
●
In hexadecimal input fields, the keys enter the hex values E and F, respectively.
●
In character input fields, the keys enter special characters and switch between upper
and lower case, respectively.
●
In numeric input fields, the G/n, M/m, k/m or x1 keys multiply the entered value with
factors of 10

or 1 and add the appropriate physical unit.
●
In hexadecimal input fields, the keys enter the hex values A to D, respectively.
●
In character input fields, the keys have no effect.
BACKSPACE deletes the last character before the cursor position or the selected char-
acter sequence. If an entire numeric value is selected, BACKSPACE moves the cursor
in front of the first digit.
