Furthermore, when you turn the knob slowly during fine-tuning, subsequent move-

4.5.3 Touchscreen
Access: "Settings" > "Frontpanel" > "Touchscreen".
Capture region
Defines the number of pixels around each element (e.g. button, icon, data point) that
create a capture region. If you tap your finger or click the mouse pointer within this cap-
ture region, this element is considered to be selected. If you tap or click outside this
area, a different or no element is selected.
The larger the region, the easier is it to select an element. However, when selecting
data points, for example, a large frame does not allow you to select precisely.
Drag threshold
Defines the maximum number of pixels around an element (e.g. data point) within
which your pointing device must stay to "click" the element. When you tap or click a
specific element and move your finger or the mouse outside this range, it is considered
to be a "dragging" or "moving" operation.
Calibration
Opens the touchscreen calibration application. Only users with administrator rights can
fulfill this task.
