I have an Excel file that is linked to a Powerpoint presentation. The presentation has a blue background, so the Excel text needs to be white. When I format the text to be white so it displays correctly in the presentation, I can not longer see it on the standard white background while editing within Excel. I do not want to change the background color within the cell using cell/format because the background shows up in the powerpoint presentation where I don't want it. How do I change the background in Excel for editing purposes ONLY.
