推荐答案

垂直选项卡用于加快打印机垂直移动。一些打印机使用具有各种突片点的特殊突片带。这有助于调整表单上的内容。 VT到头空间，填充头，VT到体区，填充行，VT形成页脚。通常它在程序中被编码为字符常数。从键盘，它将是 CTRL - K 。

Vertical tab was used to speed up printer vertical movement. Some printers used special tab belts with various tab spots. This helped align content on forms. VT to header space, fill in header, VT to body area, fill in lines, VT to form footer. Generally it was coded in the program as a character constant. From the keyboard, it would be CTRL-K.

我不相信任何人都有理由再使用它。大多数表单是以打印机控制语言生成的，如postscript。

I don't believe anyone would have a reason to use it any more. Most forms are generated in a printer control language like postscript.
