I have scanned the manual without success.
 
Adding new product
On the Description Tab there is a field " Meta Data > Link Title " What does this do?

Link Title is a new field for <a> attribute. It means everywhere where there is present a link to the product if you hover your mouse over this link you will see Link Title value, for example like on this image:
