Bug 1569

If you use the trigger and want to move to view to the trigger position, 
and if you zoomed in to a deep level, it's necessary to zoom out first and then zoom in at the trigger position to see the signals after the trigger occurred. It's also possible to scroll to the trigger position, but this can take a very long time, depending on the zoom level.

It would be helpful to move the view to the trigger position when a key pressed and/or context menu action. The current view position should be adjusted so that the trigger is inside the displayed view. If the trigger is already in the current view, nothing should happen.

A possible refinement: If the trigger is not in the current view, the trigger could be placed near to the left edge, the middle, or near the right edged of the view.

The same movement could be helpful to move to the marker positions.
