Apple Motion 4 - Manual (Page 567)

By default, only the animated parameters are active in the graph. Turn individual
parameters on and off by clicking the activation checkbox to show or hide them in the
graph. You can choose to display all parameters associated with a particular group or
object by checking or unchecking the checkbox for that group or object.
Animated Curve Sets
Alternatively, you can elect to view only the parameters that are currently animated—in
other words, parameters that already contain one or more keyframes. The next options
in the Show pop-up menu display these dynamic parameters.
To view only animated (keyframed or behavior-influenced) parameters
Do one of the following:
µ
Choose Animated from the Show pop-up menu.
µ
With the Keyframe Editor active, press U.
Any parameters with one or more keyframes are displayed.
To view parameters that have been changed from their default values
Do one of the following:
µ
Choose Modified from the Show pop-up menu.
µ
With the Keyframe Editor active, press Y.
This option shows only the parameters that have been modified from their default values,
or are currently being modified (in the Canvas, Inspector, or HUD).
To view only parameters that are currently active
µ
Choose Active from the Show pop-up menu.
When Active is selected and you are moving an object around in the Canvas, the X and
Y Position parameters and curves are displayed.
Related Curve Sets
The next six options in the Show pop-up menu display specific parameters, animated or
not. If you need to check the position of several related objects in a project, using the
Position curve set makes this a lot easier. Multiple related curve sets can be displayed at
the same time so you won’t have to switch back and forth between them. Each of these
built-in curve sets has an associated keyboard shortcut.
