Tags
----

Any object on the reference frame can have user-defined short string, so called `tag`. Tags are
used to provide additional identification to objects on an exported charts. For example, when 
you assign a tag with GCVS name to your variable star; the caption 'var' and the GCVS name will
be printed on the chart next to the star. Please note, that objects that are not selected can 
have tags, too.

Tags are stored to a :ref:`catalog file <catalog-files>` and they are loaded to the project when 
you use the catalog file as a reference frame in the :ref:`matching <match-stars-dialog>` step.

To assign a tag to an object or edit existing tag, place a mouse cursor over a detected object, 
it is highlighted with a cross hair (3). Open a context menu with a single click, and select
:menuselection:`Edit tag`. A new dialog appears. Enter a text (single line) and confirm the 
dialog. The text should appear next to the selected star.

Tags can be removed from the same context menu.
