Using the same GREP on all paragraph styles

You could spend on a Typifi product that makes GREP event activities part of the InDesign document.

Or simpler, use this script that can send GREP expressions into multiple paragraph styles all at once:

InDesign: A simple GREP editor | Peter Kahrel

That way, you don't have to set up Based-On dependencies, which can become complex and confusing (at least to me) and you can keep all styles independent, yet still edit your GREP in one dialog box interface and affect all paragraph styles at once.

Well, a GREP style certainly does seem like a good fit for your "new problem."

One thing to note, if you set up your paragraph styles in a logical order, starting with headings, working down through body, and on to bullets, footnotes, etc., you can make use of the "based on" feature to cause your "lesser" styles to inherit GREP styles from their parents, i.e., a bullet style based on the body style inherits the body style's GREP styles, along with nested styles, line styles, etc.

And, if you need a GREP-replacement to affect the whole document, just run it through Find/Change rather than relying on styles.

Hi Coops:

I would set up the character style for the numbers first.

Then move on to defining the body text paragraph tag, with the nested GREP style for the figures. When you create the other body styles like quote, bullet lists, and numbered lists, be sure to base them on the body text tag so that they pick up the nested GREP style from the parent style.

Headings don't always have numbers, but if they do, repeat the same process for the title, and then base the subtitles, figure titles, table titles off on the title tag so that they too pick up the nested GREP style from the parent style.
