The other day, I was typing and went back and change a thing or two. I needed to put a space between a couple words and instead of moving the text to the right to accommodate the space, the text was overwritten! It did this no matter what letter I typed. I ended up having to re-type an entire paragraph because of it. After I rebooted, the problem was gone. Any idea why this happened?
Ahh, you were a victim of the Insert key!
Somehow during the course of your typing, a stray finger accidentally tapped the Insert key. Normally, you can squeeze words between other words with no problem. Tap that Insert key, and you’ll overwrite instead of insert. Next time that happens, just tap the Insert key again to get back to normal.
Guess it should have been called the Overwrite key…
