# Sections & Markers

Sections and markers are timeline elements which allow you to organize your Timeline, introduce Cue triggers and introduce automatic actions.

* **Section**: used to split a timeline into separate parts. Very often used as Cues.
* **Marker**: used to demarcate a specific point in the timeline. Often used to trigger automatic actions.

Sections are used to split a timeline into separate parts.

Another purpose of sections is that they are very used as Cues and triggered either manually or with external signals, such as DMX or OSC.

Sections can also be synced to external timecode.

They can also trigger a specific Play state

Or trigger other actions (such as Timeline jumps).

Similarly to a section, they can also be used as a cue.
