What is a vertical tab?

Question

What was the original historical use of the vertical tab character (\\v in the C language, ASCII 11)?

Did it ever have a key on a keyboard? How did some

Answer 1

It was used during the typewriter era to move down a page to the next vertical stop, typically spaced 6 lines apart (much the same way horizontal tabs move along a line by 8 characters).

In modern day settings, the vt is of very little, if any, significance.
