The general purpose knob and the left and right arrow buttons can be used to set
values in numeric input boxes. The knob icon is displayed close to the box to
show that you can use the general purpose knob to enter values. The general
purpose knob is used to increase or decrease the value of the digit indicated by
the underscore. Rotating the knob to the left decreases the value and rotating it to
the right increases the value. Figures 2-12 and 2-13 show the general–purpose
knob, the arrow keys, and the appearance of a menu element that can use the
general purpose knob to enter numeric values
