Sometimes when I am working on a document I have to get up and leave, but I’m not sure if I’ve saved it or not. A quick glance at the red close button shows me the status of the document. When you look at the close button in the upper-left corner of the window, look for a little dark dot in the middle of it. If you see the dark dot, then the document has not been saved. No dark dot means that the document has been saved and no changes to the document have been made since it was last saved. See the illustrations below.
This document has not been saved.
