Is it possible to bulk replace all instances of the carbon dioxide molecule notation CO2 with the proper notation (subscript 2)?
Open the full Search&Replace tool (Ctrl
H
) and enable “Regular expressions” under “other options.” In “Find” write
(?<=CO)2
and click “select all:” all the “2” after a CO will be selected. Alt
Tab
to go to the document and now you can apply the formatting to all those “2” either as direct formatting (Ctrl
Shift
B
) or by applying a character style.
…and Replace all: with ₂
.
