Fired when a new marker is added to the model. Also fired when a collapsed model selection that is inside a marker is converted.
addMarker is a namespace for a class of events. Names of actually called events follow this pattern:
addMarker:markerName. By specifying certain marker names, you can make the events even more gradual. For example,
if markers are named foo:abc, foo:bar, then it is possible to listen to addMarker:foo or addMarker:foo:abc and
addMarker:foo:bar events.
If the marker range is not collapsed:
- the event is fired for each item in the marker range one by one,
conversionApi.consumable includes each item of the marker range and the consumable value is same as the event name.
If the marker range is collapsed:
- there is only one event,
conversionApi.consumable includes marker range with the event name.
If the selection inside a marker is converted:
- there is only one event,
conversionApi.consumable includes the selection instance with the event name.
