The "Undo" button is a function in excel that retains recent
spreadsheet entries. This is using up precious memory space that I
would like to use for other purposes. In other words, I'm willing to
give up the "Undo" function for more memory space. Is there a way that
I can "turn off" the "Undo" button, so previous worksheet entries are
not saved in memory? Any ideas you might have would be greatly
appreciated. Thank You!
