While getting used to the system I de-highlighted some words I do not know and need to make LingQs for. Is there any way to restart a lesson or get all to words in a dialogue highlighted in blue again? Thanks.
Just highlight each one with your cursor, and they’ll turn blue again.
There’s no way to reset an individual lesson, but as Jingle said above you can simply highlight the words that you don’t know then save them as LingQs.
