What does Scroll Lock Do? Have you ever wondered how to use the Scroll Lock button at the top of your keyboard? In Microsoft Excel, the scroll lock is a useful navigation option. Typically, with scroll lock off, you use the arrow keys to move the active cell pointer around a fixed worksheet. The active cell location changes with each arrow key pressed. When you use the scroll lock option, the active cell pointer remains in the current cell and the sheet moves rows or columns depending on the direction of the arrow key pressed. This option is very useful when you want to view other areas of the spreadsheet without losing your current active cell position.
