Graph selection
The interactive graph view lets the user select one or multiple components (nodes or edges). The selection affects the surrounding graphical interface (properties for the selected element(s) is shown), as well as some actions which use the selected components as input.
Interactive selection
Components can be selected directly on the graph view: clicking on a component selects it. Note that a simple click will first clear the current selection. Maintaining the control key allows to add or remove components to the selection.
