I verified that the hamburger button in the composer isn’t labeled. Specifically, this is the toggle-toolbar button in the composer-toggles component. This button is only rendered in the mobile view.
What would be a reasonable label for this button? Maybe “Formatting”, since many of the toolbar options are formatting related? Not all of them are, though. Maybe the more generic “Tools” would be better.
It occurred to me that, to enable accessibility fixes to reach Discourse’s worldwide user base without imposing too much on translators, we should use existing strings for unlabeled controls when it makes sense. So, for the hamburger button, would it make sense to use “show more” as the title? We could use “options”, and I think that would be a better fit, except that there’s already an “options” button in the toolbar itself. I think that would be confusing.
@Matt_Campbell 기존 텍스트를 재사용하는 것이 유리하다는 말씀이 맞지만, 라벨이 "[표시/숨기기] 컴포저 툴바"라고 표시되도록 두 개의 새 문자열을 추가했습니다. "옵션"을 사용하는 것도 고려해 보았지만, 해당 버튼이 토글 버튼이라는 점을 고려할 때 충분히 설명이 되지 않는다고 판단했습니다.
