Preview an item
When working in the Backlog, Team Backlog, Quality, or Defects modules, you can use the Preview pane to quickly view basic details about an item without needing to open the item itself:
From this preview, you can:
Edit the item's description
Tag an item
Change the phase of the selected item
To view the Preview pane, select the Preview tab from the right navigation pane and select an item in the appropriate module. The preview is also available when selecting items in another entity, such as selecting tests to add to a test suite or defects to associate with a test.
