Old guy not good with computers, just so you know. On my Mac Excel spreadsheet I can't change the "ruler" to show size in Inches instead of pica? Can't find how to change in Preferences.
Can you please help?
An old guy here too (78); unlike you, however, quite comfortable with computers. But I haven't been able to find any ruler in anything other than inches, and that in the "Sheet View" mode....
The only other place where something like that may show up is in the Print and Print Preview set up.
Could you do me/us a favor and describe (1) where you're seeing this "pica" unit that's concerning you, and perhaps (2) why it's an issue: what is it preventing or making more difficult for you?
