Marking Attributes for Keyframing

The workflow for keyframing using marking consists of the following:

Selecting attributes to be marked.
Changing values.
Setting keyframes for all marked values.

So the first step in setting keyframes for animation is marking which attributes you wish to animate. Almost all attributes can be marked for keyframing. You can mark attributes for keyframing in either the tool UI, Composition Browser, or Animation tab UI.

To mark an attribute for keyframing in the Tool UI:

Select the attribute label to turn marking on or off.
The label and value editor change to yellow, as in the following example where the Hue and Saturation of the CC Basics tool have been marked.

You can also mark attributes by right-clicking a value editor and choosing one of the following options:

Select:	To:
Mark Tool	Mark all animatable attribute labels of the current tool. Note that this is only available if no attribute is presently marked in the tool node.
Mark	Mark current attribute label.
Set Key	Set keyframe for current attribute value field—see Setting Keyframes.
Set Expression	Set expression for current attribute value field—see Validating and Applying the Expression String.
Reset	Reset the values to default state.

To mark an attribute for keyframing in the Composition Browser:

Expand the tool channel to the attribute level (in this example, the Hue and Saturation attribute of the Master range of the CC Basics tool).
Select the radio button of each attribute that you wish to mark in the M (mark) column.
The Hue and Saturation attributes are now marked for keyframing.

You can also mark attributes in the Composition Browser by right-clicking an attribute field and choosing the same Mark and Mark Tool options provided in the tool UI.

To unmark an attribute in the Animation tab:

Do one of the following:
- Click on the attribute label.
- Right-click the attribute field and select an unmarking option.

Select:	To:
Unmark All	Unmark all animatable attribute labels of all current tools in the dependency graph.
Unmark Tool	Unmark all animatable attribute labels of current tool.
Unmark	Unmark current animatable attribute label.

You can also unmark attributes in the Composition Browser by right-clicking over an attribute field where you will be given the same Unmark All and Unmark Tool and Unmark options provided in the tool UI.
