cobby provides no short-cut to delete products, but you can use cobby to mark products for deletion:
Simply change the name of unwanted products to "DELETE ME", hit save and switch to your Magento backend. There you search for all products with the name "DELETE ME", mark them using "select all", then Delete from the actions dropdown menu and click submit.
1. change names in cobby,
2. filter for those names in Magento,
3. select all of them,
4. select delete and submit request.
This whole process is a two step design (cobby+Magento), because we want our customers to make concious decisions when executing tasks of this kind.
