The alignment of annotations on the editable tier can be modified by dragging with the mouse. When the mouse hovers over an annotation it is highlighted in green. Depending on the position of the mouse either the whole annotation can be dragged, or the left boundary or the right boundary can be modified. When the mouse is over an annotation, pressing the Backspace key or the Delete key deletes that annotation.
The right mouse button context menu contains items for zooming, for changing the font size and for deleting the annotation at the position of the mouse click. Zooming can also be done with the zoom slider in the lower right corner of the segmentation view.
