YES PLEEEEEEAAAAASSSSEEE.

and a big YES please from me. The author insists on loads of capitals everywhere, I want to find the heading style and change All Caps to Title Caps, it would save sooooo much time!

I agree that this would be a great feature to have within InDesign's paragraph or character styles.
I've been having to use lowercase much more often for titles, and it would save a step or two.

I neeeed this! Pleeeeeeease please please fix this Adobe <3

@Raphaël:

Using the OpenType All Small Caps is of course the correct way to go; but sometimes, you’re forced by circumstances outside your control to use fonts that do not support this feature and rely on special small-caps fonts, in which case text needs to be all-lowercase to give the same result.

Adding my vote, with the note that the reason for not being able to use the Change Case command is that I need the style for TOC reference text where the original text should not be modified.

Could I also point out that when you throw small caps into the mix, it is possibly better not to merge setting the desired character case (as in Change Case command) and setting the upper/lower case appearance (small caps etc).

Still waiting for this feature.

For whatever reason the lowercase and sentence case options are available from the top menu under Type, but are not enabled in the paragraph style options. Please cross-enable the features. I recently had a client change the ingredients in a 200 page recipe book from sentence case to all lowercase. I ultimately ran a find and replace by style using GREP code, but it would've been much easier and more efficient to be able to build this into the styles.

This would also be helpful for data merging addresses where the customer wants all lower case addresses.

Please add this feature!

How is this not an option yet???

Please add all the case options in paragraph styles.

WHY ISN'T THIS A OPTION ALREADY????
Seriously, all the coding has been done (probably), please make an effort to make as much as possible controllable via paragraph and character styles.

Big thumbs up on this one! Huge time saver.

Yes please! Add all the case options in paragraph styles. Currently amending a 100 page document :-(

I, too, have a multi-page document for which having Title/Sentence case in the Character/Paragraph Styles would simplify its production.

Why can’t you just use the ALL SMALL CAPS feature for acronyms?

PLEASE ADD lowercase TO THE CHARACTER STYLES!

Please, let us set lowercase and Title Case to paragraph and character styles. This is way overdue.

Going a little beyond the initial request, it would be useful if title case followed the rules about which words are not to be capitalised: usually, articles, conjunctions and prepositions that do not occur as the first word in the title.
