Avid Freehand user and fan here...
Freehand has an outstanding tool called "Find and Replace Graphics" which allows you to find all the colors (and many other attributes) in a document, page or selection and change them to another color o=in one easy step. I have been trying to find a way to do this in Illustrator but have not been able to. Illustrator's "Find and Replace" seems to be aimed at other things. Am I missing something? It's such a usful tool, it seems Illustrator should be able to do this.
Can anyone help.
Try using the Select>Same menu item. It will allow you to select lots of different Object attributes. It still doesn't work on Type by size.
