Adding and using animator properties
You can add as many animator properties to a layer as you want, and you can combine them in a variety of ways--adding more animator properties to an existing animator group (which contains a selector and an animator property), adding a new animator group, or adding a new selector to an existing animator group.(See Understanding the Range selector).
To add an animator group to a text layer:
In the Timeline window, select the text layer and choose a property from the Animate pop-up menu. A new animator group, along with a selector and the chosen animator property, appear in the Timeline window.
To add a new animator property to an existing animator group:
In the Timeline window, select the animator group to which you want to add and choose the property from the Add pop-up menu; then choose a property from the submenu. The new animator property appears within the same group as the existing animator property and shares the existing selector.
