Time for action — controlling channel display with the header
Sometimes you want to be able to see the channels for all the objects when working on one. There is a button that will let you display the F-Curves for all visible objects:
In the 3D View, click on the Camera with theRMB.
In the Graph Editor header there is an arrow button which is highlighted in the following screenshot. Click it with theLMB.
Do it several times and watch the Graph Editor and the Channel Selection Panel.
What just happened?
The arrow button toggles whether only the F-Curves relating to the current object are displayed or whether the F-Curves for all visible objects are displayed. The ghost next to it allows you to display the F-Curve of objects that are not displayed.
