Selecting Nodes
To select a node, click on it in the graphical editor.
The focused node is indicated by a frame. The value fields to the left of the graphical envelope editor display the parameters of the focused node.
If multiple nodes are selected, you can use the Env Node pop-up menu to set the focus to a different node without losing the current selection.
To add a node to a selection, Shift-click the node. Selected nodes are edited together.
You can select multiple nodes by drawing a rectangle around the nodes with the mouse.
If the graphical editor has the focus, you can select the next or the previous node with the left and right arrow keys.
