Sections represent significant self-contained parts of the timeline. Common examples of a section are a verse, a chorus, or a bridge in a song.

Currently, sections are only exposed as editor actions that are available when a range is selected on the timeline:

When Ardour treats a range as a section, it cuts or copies audio and MIDI data and their automation across all tracks. When pasting the cut or copied data, it ripples all tracks at the edit point.
