The Composition Browser displays all the nodes for the current composition. Using this browser, you can view parameters and set keyframes for animation. It's also an easy way to quickly view parameter names when referencing them in expressions.

The Composition Browser has three columns. The Name column contains the name of the node or attribute. The Value column contains the value associated with an attribute. The M (marked) column indicates whether an attribute is marked for keyframing.

The Composition Browser is also available in the Animation tab of the tool UI.
