Yikes! Disappearing Text

Overtyping: Here’s a tip to keep you out of the asylum. If while revising a document, your new typing seems to vacuum up the text that follows, you are “overtyping.” There is a good chance you accidentally hit the Insert key (located just to the right of the Backspace key). If at the bottom of the screen on the status bar, you see OVR darkened, you are in the overtype mode. To turn this off, just hit (on purpose this time) the Insert key or double-click OVR on the status bar.
