**
It is real.
One day a friend told me that he worked in the lab late till 2 O’clock at night. I asked him “what took you so long?”
He said that he was working in M.S Word. His supervisor made some corrections and told him to finish it the same day.
He started typing again and making corrections in the old document. Now when he pressed any key it was erasing and over writing the old one. He tried a lot but can’t understand. So he had to type the whole document again and do the all work from the beginning.
I told him that he just needed to press the “insert” key on the keyboard and it wouldn’t have taken so long.
He had been using computer for more than 3 years at that time.**
