To view the target of a pointer or to view one element in an array or structure, double-click on the entry. TotalView replaces the contents of the window with a view of the item you dived into (or the object it points to, in the case of pointers). This allows you to easily chase chains of linked structures.
After you dive into a field, you can edit its contents. (Diving into a substructure is the only way to edit the substructure’s value.) You can also cast individual entries in arrays to different data types for display.
