Accidentally hit (and discovered) the Accessibility Check feature in @libreoffice At first it seemed, every time I used italics, it faulted me for “The text formatting conveys additional meaning." I'd be quite happy to use something more semantic. there is an “Emphasis" character style, for instance. I can even set it to turn on when I do cmd-I. But not turn off again. So that's useless. Unless someone can tell me how cmd-I can toggle it. (and bold/strong-emphasis for that matter)
