You can press Command-Option-Shift-L (or ctrl-alt-shift-L) to override all master page objects, but that is only for one spread at a time.

However, remember you do not need to override the master page items to place (using File > Place) into them. You can do that without ctrl-shift-click on them.

Thanks for the update, Sarah. Yup, form fields are PDF only.

Radia: Wow that question has nothing to do with this thread, does it?! :-)
However, the quick answer is: It depends on how you make the PDF file. If you choose Convert to Destination (Preserve Numbers) then it will usually convert to CMYK. If you choose No Conversion, it will leave them as RGB.

Just to clarify: You want the script to name the file the same thing as the code?

You’re saying that this font definitely does not have those fractions? Have you looked through the font carefully in the Glyphs panel? Sometimes fonts have simple fractions like this that you wouldn’t expect.

But yes, you can definitely search for things that look like fractions and replace them with other things with grep.

I don’t think that is possible in InDesign by itself. It may be possible with Power Headers from In-Tools.com
