I’ve been having trouble with LibreOffice because I can’t figure out how to have it autofill the kana when I insert Furigana over kanji (i.e. the phonetic supertext, when typing in Japanese). This autofill for furigana is a standard feature in MS Word, so it is expected by instructors, etc., that I would have that ability at home. Manually filling in the furigana is extremely time-consuming. Please let me know how can I enable the autofill.
