Viewing tags highlighting

Last published : Oct 15, 2026
Arctera Surveillance provides the option to highlight tags applied to the item you want to review. Tags are highlighted only if the items are applied with at least one tag. The Labels & Item Statistics pane lists all tags and hotwords associated with the selected review item.
An item can have multiple tags associated with it. Hotwords and tags are highlighted in the Preview pane for emails and collaboration messages. Hover over the highlighted content to view all the hotword searches and tags associated with it. When an email contains both hotwords and tagged instances, hotwords are highlighted in yellow, tags in green, and the currently selected hotword or tag in orange color.
Note: When the tags suggested by Arctera Classification have a content match length exceeding 300 characters, Arctera Surveillance does not highlight those tags in the Preview pane.
