Choose the Maintenance menu to directly manipulate
  objects (tests, collections, groups, variables, and
  history records) in the DTM library.

  After you choose an operation from the menu or one of
  its submenus, use the resulting dialog box to view and
  specify options.

  Operations in the Maintenance menu apply to the current
  selection in the active view window.

  Before beginning an operation, click on (highlight) the
  selection on which you want to perform the operation.
  Then choose the operation you want to perform from
  the menu. DTM automatically fills in the name of the
  selection in the text field of the resulting dialog
  box.

  If you do not make a selection from the active view
  when you begin an operation, you must enter your
  selection in the text field in the dialog box. Multiple
  entries are generally accepted.
