Open node(s)...

Displays a dialog box for editing node parameters for all nodes which are selected with the current selection mode. If more than one node is selected, a sequence of node dialog boxes will appear, according to the order you selected the nodes. You can break this sequence at any stage by pressing the “Option key” while clicking “OK” or “Cancel”. 

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