It is possible to apply the style of a node template from yEd's palette to an existing node. To do that, select the node you want to adjust in yEd's editor area, right-click the desired template in yEd's palette to open its context menu, and choose "Apply" or "Apply Type". Since yEd automatically populates the "Current Elements" palette section with the styles used in current editor tab, it is also possible to copy the visualization from one existing node to another existing node in this way.
