I have no idea of how to use the Insert function-
Dear Jackie,
Coming late to this thead...Insert is a frustrating key. By default it's on. That is, if I write a sentence and forget a word, and I go and put my cursor where I forgot the word, and type the word, the other words move over - I "inserted" the word. If you press Insert, it turns this function off. They used to call it "TYPEOVER" in old WordPerfect. So, if you've pressed Insert, you're in Typeover mode, meaning that each letter you type REPLACES the letters "underneath" it rather than them all marching over to the right like you're used to. In Word, three little letters "OVR" appear on the bottom status bar when you've got it switched to Typeover. In other programs you have no way to know if you've switched it on or off!
In other words, the Insert key toggles the Typeover concept on and off. You don't really "use" it like you do, say, the space bar.
