Using the Hierarchical View

On the left of the Curve Editor is a hierarchical view of the curves and expressions that have Show Curve enabled. You can use this view to expand and collapse the parameters, lock the curves against editing, and toggle the curves that are shown in the Curve Editor graph.

Expanding or Collapsing a Curve

Double-click on the part of the parameter name to expand or collapse.

OR

Click to expand or to collapse.

Note:  Collapsing a parameter in the hierarchical view only changes whether its children are displayed in the hierarchical view. Its only use is to keep the hierarchy more manageable.

Selecting a Curve in the Hierarchical View

Click on a parameter name to select its curve - it must be the leaf name as that corresponds to the actual parameter.

Tip:  You can select more than one parameter by Ctrl+clicking further parameters and Shift+clicking to select all the parameters from your last selection to where you click.
