As elements are added to the Elements Explorer, Test Studio uses an
intelligent element identification scheme to auto-generate find expressions.
When an element is ready to be added to the Elements Explorer, Test Studio tries
to use the first item in the list (usually "id"). Using this criteria, if the item
is unique for the entire page, the element is added, a find expression is
created, and Test Studio stops evaluating. You can add new tags to the list,
reorder them, or delete them (except for TextContent and TagIndex which are
locked from deletion).
