With GeoMedia 6.1 you’re now able to do a find on a text feature class based on the symbology (color, font, size, style, etc.) or contents (literal value of the text). Then you can edit the text to match different business needs. For instance, you might have created rich text that is 14pt and red. You can use this command to find all of this text and change it to 12pt green.
I’ve since this before in products like Adobe Illustrator and the former Macromedia Freehand. Though they probably aren’t too useful strictly in a "GIS" sense, they can be very useful when looking at cartographic output.
