To animate an object across the screen by setting an initial keyframe
1 In the Canvas, position the object to your desired starting location.
2 To create an initial Position keyframe, do one of the following:
• Press Control-K.
Note: Pressing Control-K adds a keyframe to the last-modified parameter of the object.
• In the Properties Inspector, open the Position parameter’s Animation menu (the
downward arrow on the right), then choose Add Keyframe.
Note: The Animation menu (the downward arrow) and the Add/Delete keyframe buttons
appear when you place the pointer over the end of the parameter row in the Inspector.
You can also Control-click a parameter’s name to reveal a shortcut menu.
• In the Properties Inspector, click the Position parameter’s Add/Delete Keyframe button.
A keyframe is added at the current playhead position, and the parameter appears red in
the Inspector.
3 Move the playhead to a new time position.
4 Move the object to a new position in the Canvas.
A keyframe is added at the current playhead position. When you play back the project,
the object moves over the interval you set.
Keyframe Editor Controls
The left side of the Keyframe Editor contains a list of parameters. You can choose which
parameters to display by using the Show Curve Set pop-up menu at the top of the list.
This menu has an option for creating custom curve sets so you can focus on specific
parameters in the Keyframe Editor. For more information on creating and viewing
parameter sets, see Custom Parameter Sets.
There are a number of controls above the parameter list:
Show Curve Set pop-up menu: Sets what is displayed in the Keyframe Editor. The pop-up
menu items include:
• All: Displays all parameters for the selected object, whether or not the parameters are
animated.
• Animated: Displays only animated parameters and curves for the selected object. This
includes animation curves created by keyframing as well as behaviors. This is the default
setting. With the Keyframe Editor active, you can also press the U key to choose
Animated from the Show Curve Set pop-up menu.
