Do you need to modify and copy the same information on multiple products (price, quantity, availability, supplier, etc)?
Nothing is more simple with Sc and its copy/paste option: right click>copy then select the products to modify, right click>paste. That's done!
Note that this copy/paste option can be used on all fileds displayed in the central column (except the ID and the image), but also in some of the properties panels, such as variants and metafields for example.
