The keys in the DATA ENTRY keypad are used to enter numbers, units, and characters.

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 change the sign of the entered numeric value. Multiple decimal points are not allowed; pressing – for a second time cancels the effect of the first entry.

• 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 Data Entry section.

• In numeric input fields (e.g. in the numeric entry bar), the G/n, M/μ, k/m or x1 keys multiply the entered value with factors of 10(-)9, 10(-)6, 10(-)3 or 1 and add the appropriate physical unit. x1 is equivalent to OK ENTER. It confirms the previous entry and deactivates the input field (closes the numeric entry bar).

• In character input fields, the G/n, M/μ, k/m keys enter the letters G, M, K, respectively. x1 is equivalent to OK ENTER. It confirms the previous entry and deactivates the input field.  

The ESC CANCEL and OK ENTER keys are equivalent to the corresponding keys in the NAVIGATION keypad.

BACK deletes the last character before the cursor position or the selected character sequence. If an entire numeric value is selected, BACK moves the cursor in front of the first digit.
