View and change layer information

To rename a layer or property group, do one of the following:
- Select the item in the Timeline panel, press Enter (Windows) or Return (Mac OS), and enter the new name.
- Right-click (Windows) or Control-click (Mac OS) the item, choose Rename, and enter the new name.
To alternate between viewing the names of source footage items and the names of layers in the Timeline panel, click the Layer Name/Source Name column heading in the Timeline panel.
To show the name of the source footage file for a selected layer in the Info panel, press Ctrl+Alt+E (Windows) or Command+Option+E (Mac OS).
To see what footage item is the source for a layer, right-click (Windows) or Control-click (Mac OS) the layer in the Timeline panel and choose Reveal Layer Source In Project.
The source footage item is selected in the Project panel.

You can filter layers in the Timeline panel to show only layers with properties that match a search string or certain other characteristics. See Search and filter in the Timeline, Project, and Effects & Presets panels and Showing properties and groups in the Timeline panel.

Jeff Almasol provides a script on his redefinery website that automatically writes specified information about footage items or layers to the Comment fields for the respective items in the Project panel or Timeline panel.
