The Document History panel shows the history of a single selected document, with each action taken displayed as an entry in the list. The entries are presented in a single page, sorted from most recent changes to oldest. Each entity in the list displays an action icon, the username of the person who performed the action, the date/time that the action was performed, and the Document ID number. If you need to need to focus on only certain types of actions, you can click the icon for one or more entities to toggle the filter on or off for that type of action. These are contextual; each action type has its own icon.
Note that using the Document History filter requires View History permissions and is only available when your Search Mode is Grid View.
To filter to a shorter, more focused list of actions, refer to the filtering options outlined in the View Archive History section.
