The correct answer to this question is View –> Split. This function can be used in the Microsoft spreadsheet program, Excel. This split screen feature allows one to view multiple copies of the same spreadsheet. The sheet can be split either vertically or horizontally, which can be split into either two's or four's.
Splitting the sheet makes it easier to see various areas of it at the same time. To activate this feature, one would click the View tab on the Excel ribbon. Once the tab loads, Split can be clicked to split the screen. To turn off the feature, View -> Split can be clicked again.
