Do the icons for Attachment, Edit & Link only indicate the existence of such items and not link?

Question

Also, using Attachment editor in Inspector only gives an opportunity to create a new attachment. I cannot see where I can browse to my files in Drive or anywhere on my computer and simply attach them. Also, one you create an attachment, how do you delet it?
