Yes, these particular parameters and their values allow you to get a right click link at the schematic level that will open a browser window for a url or even a PDF file at the schematic level. It does not search these as supplier links for BOM though. But you can cut/paste a link to Octopart there an quickly get reference information and price. Unfortunately, like all web links, they tend to go dead periodically but that is not a fault of CS.
I see, well yews like you say internet links are prone to change, my master is generally the manufacturers part number as I won't even rely on distributor stock numbers as they can change to or the distributor stops stocking that part.
