Selecting Graph Elements
Single graph elements are selected with a simple mouse click (left mouse button).
Important: The mouse click must occur on the visual representation of the graph element.
Multiple graph elements can be selected by opening a selection box with a mouse drag gesture that starts at an empty place within the drawing canvas.
Deleting Graph Elements
Selected graph elements can be deleted using either the DELETE key or the "Delete" item from their context menu.
Selected nodes and bends can be moved by means of a mouse drag gesture that starts at either of the selected elements.
Selected nodes can be resized by moving either of the eight knobs of their selection indication with a mouse drag gesture.
Further editing capabilities are described in section Edit Mode.
