Couple Markers
When this function is ON, moving any marker causes an equal X-Axis movement of
every other marker that is not OFF. By “equal X-Axis movement” we mean that we
preserve the difference between each marker’s X-Axis value (in the fundamental X-
Axis units of the trace that marker is on) and the X-Axis value of the marker being
moved (in the same fundamental X-Axis units).
This may result in markers going off screen.
