Arrows can be added to any row.
Define default arrow options with the Arrows options dialog:
Menu: Diagram | Arrow options
For a consistent look, you can change
Arrows within a row are managed through a dialog box listing all the row's arrows, and allowing you to add, edit, duplicate or delete an arrow.
Two types of arrows are supported, across and along arrows.
When a row is deleted, all the arrows that use it as either the start or end point, are deleted too. This includes any arrow that belongs to that row, any Across arrow that ends in that row, and any Along arrow whose guideline ends in that row.
