+## Subtitles
+The **Subtitles** tab lists the subtitle of every speech line (11 languages; choose one with *Language*).
+- Search by text or line name, filter by **Character** and **Category** (taken from the linked speech sound),

+  Russian, Polish, Japanese and Korean subtitles accept any character.
+- **Go to the sound** opens the speech line in the Sounds tab. In the Sounds tab, the editor of a speech line

+as `\n` as they are).
