Trac Ticket Batch Modification
From custom query results Trac provides support for modifying a batch of tickets in one request.
To perform a batch modification select the tickets you wish to modify and set the new field values using the section underneath the query results.
== List fields
The Keywords and Cc fields are treated as lists, where list items can be added and/or removed in addition of replacing the entire list value. All list field controls accept multiple items (i.e. multiple keywords or cc addresses).
