Open edge(s)...

Displays a dialog box for editing edge parameters for edges where both input and output nodes are selected with the current selection mode. If more than one edge has both input and output nodes selected, a sequence of edge dialog boxes will appear. You can break this sequence at any stage by pressing the “Option key” while clicking “OK” or “Cancel”. 

The “Open edge(s)…” command will be dimmed if no nodes are selected with the current selection mode.
