SpinnerNode

A widget that provides a numeric input control with increment and decrement buttons.

On caQtDM, this renders as a wheel switch (caNumeric) with digit-by-digit up/down arrows. On Phoebus, this renders as a Spinner with increment/decrement buttons. On PyDM, this renders as a PyDMSpinbox with standard up/down controls.
