Delete Keyframe
Deletes all of the selected parameters’ keyframes at the current frame. Alternatively, Ctrl-click the red
circle next to one of the selected parameters’ names.
Each parameter with a lled red circle next to its name has a keyframe at the
current frame.
Add Track
Creates tracks for the selected parameters.
Copy Track, Paste Track
Use these commands to copy tracks between parameters. First, select the parameters whose tracks
you want to copy. Choose Copy Track. Next, select the parameters that should receive the tracks and
choose Paste Track.
Delete Track
Deletes all tracks of the selected parameters. Alternatively, Ctrl-Shift-click the circle next to one of
the selected parameters’ names.
Show Track
Shows all animation tracks of the selected parameters in the Timeline.
Show F-Curve
Shows all f-curves of the selected parameters in the F-Curve manager.
Set Driver, Set Driven
Using these commands, you can create set driven keys directly in the Attribute manager without
having to open the XPresso Editor. A set driven key uses one parameter to drive (i.e. control) another
parameter. For example, you might use a set driven key to make a car’s electric windows wind down
when a character presses the switches. Almost any type of set-driven relationship is possible, making
it easier to manage complex motions or objects.
Example
 In the Object manager, create a sphere and a cube. We’ll use the sphere’s
height to drive (i.e. control) the cube’s height. So that you can see the sphere
clearly, move the cube along its X-axis until it’s next to the sphere.
