Can you force lower-case with a style?

[Thomas_Calvin]

Our TOCs pull headings from the document that are in all caps, but we don't want the TOC entries to be in all caps. I've seen examples of grep styles that can apply a character style to make letters capitalized, but I don't think I've seen the opposite. Is it possible?

Had lost track of changes in InDesign for a while, but it seems InDesign has learned Lowercase for character, dont aks since when.

As you see image1, my sample text has no uppercase switched on, its just hard UPPERCASE.
Now look into your character setting, either in the pallette, or thru an character-style. Theres a new option "lowercase" (german "Kleinbuchstaben") now.

This would be your best option i guess.

As pointed out multiple times in this discussion.

Since this question is not marked as answerd...

As for the new direction (title-capitalizing), from where should a script know, if my text is really uppercased? Just have a acronym or so between somewhere. This could be a job for a LLMA.

The initial error was to ditch upper/lower-infos by converting the text to upper.

A string comparison in a script will still know.

So it would appear that since July 2024 with the 19.5 version of InDesign, we all now have the ability to Find/Change: Change Case: lowercase.

But also sneaked in: the Character panel gives the option to apply lowercase as an appearance style (but not a hard textual change as in Type > Change Case). It is also possible to make a Character Style with this new attribute as an appearance style. However, the Properties panel and especially the Control panel do not yet show this new appearance attribute button.

Have I gotten the introduction date correct?

Your solution in my case was still better, Mike. I'd rather have a title's raw bytes capitalized exactly as desired, and then style its references elsewhere.
