When I create a document which is 72 pt both in height and width, clicking neither the "actual size" button nor "100%" button in the view tab shows a 1-square-inch canvas shown precisely on the screen, which I believe should've been the normal case. Incidentally, "100%" actually is smaller than the "actual size".
However, as to a document that is 1 inch (with is equivalent to 72 pt, I believe) both in height and width, clicking "actual size" button and "100%" button both shows exactly the same and correct size of the document, which is a 1-square-inch canvas shown precisely on the screen.
Is it a bug? Or do I misunderstand any concepts?
What's the difference between 100% size and actual size? I can't really tell according to the words.
p.s.: my OS is OS X 10.11 15A279b.
