希望能增加鍵盤快捷鍵 開啟/關閉字幕顯示 方便練習聽力時先關閉 聽不懂再打開 Hopeful enhanced keyboard speedy opening/closing subtitles Convenient practice for listening, closing the subtitles first, and re-opening the subtitles when unable to listen.

Le tuve mucha fe, pero identifiqué varios errores en la traducción, cosas que no tienen nada que ver con lo que realmente están diciendo los personajes, traducciones muy literales y algunas me confundía mucho :(
