where to find "change case"?

How do I change case?

Hello,

may I don’t get your question but may be Format-> Character...->Tab: Font Effects -> Section: Effects -> Drop down: Case is what you are looking for.

Hope that helps.

Warning! This is a formatting directive, it does not change the text case, while Format>Text>various menu items modify the text.

The advantage of your suggestion is the text remains as typed and you can change the appearance by merely customising a paragraph/character style.

But if the goal is to “normalise” typing, you must use the Format menu.

Or did you mean Format > Text > tOGGLE cASE (or Sentence case, etc)?
