I am working with a rather large vi handed over to me from a predecessor. All of the sequence structures are stacked. I need to change them to flat sequences if I have any hope of figuring this thing out. I need to find all the stacked structures and the tiny lines on the screen don't seem to be helping (and, of course, no zoom). Is there some way to list, search, highlight or otherwise identify all instances of a specific type of structure? Believe me, searching for "find" and "structure" doesn't get you anywhere.
