Add a forced 'lowercase' option in the Character panel’s menu, similar to one InDesign has
InDesign has a way to force a selected text to be always displayed in lowercase.
Illustrator does not offer this option, as the attached screenshots show.
This option would be useful for cases when a font relies mostly on lower-case characters, using its upper case for emphasis, rather than a traditional usage of it, for starting sentences and given names with capitals — not uncommon in comics.
A current workaround is to run the native Type > Change Case > lowercase each time a text gets pasted (or setting up a custom routing with third-party apps to change the text in clipboard automatically). Anyway, the InDesign’s approach is much simpler, please match the function set it has.
