A scene saves a camera angle and layer state you captured earlier. See What is a Scene? for exactly what it stores.
Rename a scene or folder
Double-click a scene's name to edit it. Type the new name and press Enter to confirm, or press Esc to cancel. Clicking anywhere else also confirms the new name.
Folders rename the same way. Double-click a folder's name to edit it.
Update what a scene captures
Right-click a scene and choose Update to recapture the current camera position, layers, and preview image into that same scene, replacing what was saved before.
See Organize Scenes to reorder scenes or group them into folders.
