A family of Microsoft spreadsheet software with tools for analyzing, charting, and communicating data.
Try opening a New Window under the View tab. This produces a duplicate of the file you are working on and then you can Alt-Tab between the two sheets.
The file name in the New Window will have a "2" added to its file name.
Be sure to close the file with the "2" in its file name first, because if you dont all the formats and view setting of the "2" file will be saved to the original file, which may not be what is desired.
There is no need to save anything in the "2" file as it is being recorded in the original file that you also have open.
Good luck I hope it helps, even though it is a couple of months after your original post
