I'm working on a spreadsheet that will track upwards of 50 different departments in my organization and their compliance with several different standards. If I were to abbreviate a department in the cell, labeling it "QM" for Quality Managment, is there a way to have just "QM" displayed unless you roll your mouse over the cell, then the unabbreviated name (Quality Management) is shown? I realize I could just make this a comment, but is there a quicker, maybe even an automatic way to do this?
