The NumericUpDown.Accelerations property can be used to increase the speed with which the System.Windows.Forms.NumericUpDown moves through a large set of numbers when the user holds the up or down arrow, either with the keyboard or with the mouse. Setting this property will decrease the number of NumericUpDown.ValueChanged events that occur depending on the NumericUpDownAcceleration.Increment and NumericUpDownAcceleration.Seconds property values specified for each System.Windows.Forms.NumericUpDownAcceleration object in the collection. The System.Windows.Forms.NumericUpDownAcceleration objects contained in the collection are sorted by their NumericUpDownAcceleration.Seconds property.
