For starters, you're going to have to use the correct font names, including correct capitalization. The property you want to change is "applied font", not "find what". And it would probably be more sensible, to go through all paragraph and character styles and make the changes there first, otherwise you'll have troubles again every time you edit stuff.
So start off by getting the name of the font used in every paragraph style, and loop through your list to see if they should be changed. Do the same for character styles. And then do the find/change to find any that have been applied manually.
That's a good idea.
I was thinking of actually setting up a new style sheet for each one with the new open type font and then doing a find and replace on the styles.
If I get that going, then I may take a crack at trying to write a script that would do a find and change of style sheets.
That seems like a more realistic goal.
Did you got the script to edit the bunch of style sheets?
Once of our client demand to make all the H&js in a specific way. So I really need such a script.
I'm sorry...we never got it to work.
They just replaced them all manually.
I wonder if you could put something out on the forum that maybe could achieve this using GREP?
