How to: Cancel Work Item Changes
If you start to edit an existing or new work item and then decide that you do not want to continue, you can undo your changes. Work items and queries that have unsaved changes are marked with an asterisk (*) on the tab, or a pen icon in the results list.
To perform these procedures, you must be a member of the Contributors group or have the View work items in this node, and Edit work items in this node permissions set to Allow. For more information, see.
