Viewing Work Item Details
To view the full details of a work item, click its link (key or summary).

This will open a pop-up version of the Jira work item page, where you can edit the work item, view and add comments, share, view history, and more. For specific information on working with and editing work items, please refer to the Jira documentation.

You can also quickly edit many work item fields directly from the structure. See Editing work items from Within Structure.
