It’s the vertical line that blinks in text boxes and documents when you edit. Other than that I don’t know much about it.

      Yes , the link I provided also explains the etymology of “mouse”. In short, the invention of a free moving cursor was initially called a “bug”, but since the caret cursor was also called a “cat” they called it mouse. The first mouse pointers were operated by trackballs, so the physical device didn’t resemble a mouse until later.
