own-caret in editor<%>

Tells the editor to display or not display the selection.

The focus state of an editor can be changed by by the system, and such changes do not go through this method; use on-focus to monitor focus changes.

• (send an-editor own-caret own?) -> void
     own? : boolean

  Propagates the flag to any snip with the editor-local focus. If no sub-editors are active, the editor assumes the caret ownership.
