# Numeric pop-up keypad keys

Use the keys on an external keyboard or keypad (where equivalent keys exist) in place of any of the buttons in the numeric pop-up keypad.

Keys | Descriptions
--- | ---
Decimal | The decimal button (.) on the pop-up keypad is visible only if the decimal point type is Implicit. If the decimal button is visible, you can also use the decimal key on an external keyboard or keypad.
Minus | Press the minus button (-) on the pop-up keypad or the minus key on an external keyboard or keypad to toggle the value between positive and negative.
Escape | To close the pop-up keypad without writing the value to the Value connection, press the ESC button on the pop-up keypad or the Esc key on an external keyboard or keypad.
Backspace | To delete the right-most digit, press on the pop-up keypad or external keyboard or keypad. Hold the button down to delete multiple digits. If there are no digits left, the minus sign, if any, is removed.
Enter | Press on the pop-up keypad or on an external keyboard or keypad to write the value to the Value connection.
Delete | Press the Delete key on an external keyboard or keypad to clear the scratchpad.

Tip: | If the graphic display is changed remotely before the operator has pressed the Enter button in the pop-up keypad, the keypad closes without writing out a value. If the computer’s resolution is smaller than 124 pixels wide by 240 pixels high, the pop-up keypad cannot open.
