Using Markers to Edit Events
Using Markers to Edit Events
You can use markers to define or modify the position of an event on the
A->B or B->A trace.
Markers are available when you modify or add an event.
If two markers are located at the same place, both will move together.
To move a marker:
1. If you intend to move the markers directly from the graph, ensure that
the button is selected in the zoom button bar.
2. From the Edit tab, press the buttons corresponding to the markers that
you want to move. The buttons will turn yellow, indicating that a
specific marker is selected.
Selecting marker A or B will move the a-A or B-b pair. However, it is
possible to only move the a or b marker by pressing on the
corresponding button. You can also select the four markers if you want
to move all of them at the same time.
