Function
The Scroll Lock key was of great use in the DOS era. Due to the technological limitations of that era, the computer display screen could only display text that was 80 characters wide and 25 lines long. In this way, when we are reading a document, we can use the Scroll Lock key to scroll through the pages very conveniently.
After entering the Windows era, with the development of technology, the role of the Scroll Lock key has become smaller and smaller. Now the places where we can use the Scroll Lock key are probably in word and Excel. In EXCEL, when Scroll Lock is turned off, when you use page turning keys (such as Page Up and Page Down), the selected area of cells will move accordingly. But when we press the Scroll Lock key, the selected cells will not move. In word/excel, press the up and down keys to scroll, lock the cursor and scroll the page at the same time! If this key is not pressed, pressing the up and down keys will only move the cursor but not scroll the page!
