line segment and a marker that can shift along the displayed line.
It represents an interval with a current position. The current
position can be changed by dragging the marker, by clicking the
displayed line, by clicking arrow buttons at both ends of the
displayed line, by using the cursor keys or by using page-down or
page-up.
