On the far right, there are four abbreviated words: REC TRK EXT OVR, each with a small circle to their left. Nothing is listed on any of the menus, or when I searched the help field (that's because the Mac calls it 'overtype,' which I didn't know at the time).Īt the very bottom of the document's screen, there are some bits of information (page, section, total number of pages, etc.). So I was typing along in Microsoft Word on a Mac, when all of a sudden I was writing over all of the text - as if I had pressed the Insert key on a PC.
