What's keeping you from using those spellings now?
Just Big rules we have, this is just a small example of the big rules with in other examples below with uppercase first letter and in some cases all letters in names:
Cold Weather Accessories
Key Collection Statement
Royal Velvet Fashion Bedding
We get documents and we proofread them and then we apply this rules across the board to emphasize importance in the documents. I hope that makes sense.
A dictionary probably won't help you, but a find/change by list script would....
OK, I like this option.
How does that work? Can you send an example of how to use a list script within the find/change option?
I have used the find/change option before, but never used a list script.
I'm going to suggest you move this over to the scripting forum: InDesign Scripting
I'm not a script writer myself, but you can see an example of a find/change script that ships with ID in the sample scrips installed in your scripts panel.
