Sorry, but that did not work either. The old CO2s are still in normal

Strange... Did you really format the CO2 with subscripted "2", then selected
and copied it to the clipboard, then used
Find what: CO2
Replace with: ^c
?

Another way to do it... Use the font character for the subscripted 2
(Unicode: 2082):
Find what: CO2
Replace with: CO2

You can insert the 2 (in the Find dialog, as in the document) by typing the
code 2082 and then Alt+X.
