Don't have a PoKeys, but if it's calling for an external pull-up resistor that looks correct. I usually see a resistor value of 4.7k specified. I'm not sure how important the value is, though, as a pull-up resistor simply prevents a direct short when the switch is closed. In a circuit such as this, the Probe Input will sense a low (GND) when the switch is closed. When the switch is open, this point will sense the applied voltage (5V in this case) since the resistor is a relatively low value compared to infinite resistance of the open switch contact. Too high a value of the resistor could result in slightly less than applied voltage but it 10K vs. 4.7K shouldn't make much difference.
Bottom line, if the documentation calls for a specific value. Otherwise, a value in the range of 4.7 - 10K should work just fine. But your diagram is right on the money for this application.
