A user can take action on a document in a number of ways in Kahua.  Users can either use the Action Bar in the log, the Action Bar in the detail pane or take action by right-clicking the mouse on a record in the log.  The actions a user can take are dependent on their permissions.  A user will only see the actions they are able to perform on a record.  If a user does not have permission to delete a record, they won't see the Delete button.
