Numeric Input Using the Rotary Knob. The knob icon is displayed next to a
selected dialog box parameter when you can use the rotary knob to change the
parameter value. Figure 2-10 shows a dialog box that can use the rotary knob to
enter numeric values.
You can use the rotary knob to change the value of the numeric digit indicated by
the underscore character. Use the arrow buttons to select any digit value to
change with the knob. Rotating the knob to the left decreases the value and
rotating it to the right increases the value.
You do not need to use the front panel ENTER key to confirm a value when
using the rotary knob to change a value. The input value is confirmed automati-
cally without pressing the ENTER key.
