Reply To: Smart Title Case

Don't forget: a GREP style can only change lowercase to uppercase, since that's all that is possible with a character style. So a GREP style cannot convert an uppercase to a lowercase character to 'correct' from “InDesign Is A Rather Good Program” to “InDesign is a Rather Good Program”.

The same goes for the first word of a title — this would typically already be entered as a capital.

(Harbs' tool does not have these limitations.)

That said, A-M's GREP can be adjusted to this to change the first character as well (and it shows where the backslashes go):

(^s*l)|(<(?!(the|an?|in|to|o[rfn]|for)>)l)
