I want to thank Jordan Ayan for his helpful book, “The Official Guide to Mylio” and for his videos. No, I’m not connected to him in any way, I’m just the type of user who likes to have a written (Kindle!) reference to refer to. I’ve transitioned from Aperture to Mylio (and posted about that experience in the Aperture forum) and love it and I’m using the book to help me as I keep exploring Mylio’s features. His list of keyboard shortcuts is just one of the useful features of the book.
