Optionally, in the History pane on the left side of the window, you can double click on a changelist in the list and it'll open the details for just that changelist in a new window (same window you'll see with Edit > Go To...).
Note for this, in the newest version of P4V, the "Pending" and "Submitted" change types are combined in the goto dialog. Now there is just "Changelist" and it figures out which one it is by the number you enter.
