thank you so much dfay and Vero, you are awesome, especially dfay deserves credits for his link to absolutely accurate workflow!
By the way, I think it would be useful for others if you, Vero, pasted in the link to the workflow you've mentioned. It sounds very like that of dfay's example, but may have also a specific ring of relevance for somebody. Perhaps it sounds like asking to much, but please understand that for a Newbie like me the title of a workflow is sort of a mystery when it comes to localise it as much as many other things with Alfred app.
