 - `Archive`: Only available for Explorative Annotations. Closes the annotation and archives it, removing it from a user's dashboard. Archived annotations can be found on a user's dashboard under "Explorative Annotations" and by clicking on "Show Archived Annotations". Use this to declutter your dashboard. 
 - `Download`: Starts the download of the current annotation. Skeleton annotations are downloaded as [NML](./data_formats.md#nml) files. Volume annotation downloads contain the raw segmentation data as [WKW](./data_formats.md#wkw) files.
 - `Share`: Create a shareable link to your dataset containing the current position, rotation, zoom level etc. Use this to collaboratively work with colleagues. Read more about this feature in the [Sharing guide](./sharing.md).
