How to mark words as unknown again?

I clicked in on a japanese story about Momotaro and I wanted to skim through the pages so I naturally clicked the next arrow to do that.

To my surprise, it marked all words on that page as known. I definitely did not want to do that, I think there were like 30 words there that I didn’t know and I would like to have a chance to actually learn them properly.

I can’t find anyway to mark those words as unknown again though. I tried looking everywhere. Is it possible?

And also, why does it mark all words there as known? I really don’t see the purpose of that. It prohibits me to skim through the sentences to see if this is something I actually want to read or not.

Paging lessons automatically moves all remaining blue words on that page to known. We assume you have created LingQs for all unknown words before paging. If you do want to read the whole text, you can choose the Full Text option to see the full lesson at once without removing blue words.

Automatic removal of blue words can be turned off in the Settings for the Reader. Just click the gear icon in the top right corner of the Reader. The “Move words to known” option is the one to turn off. However, this just means that when you click the complete Lesson option on the last page, all your blue words for the whole lesson will be moved to known. There is no reason to keep blue words. The idea is that you either need to learn them or they are known. (or you can ignore words).

Having said that, you can click on all white words to make them blue again and create LingQs for them. So, if you are reading, and come across a word you incorrectly marked as known or ignored, just click on it to make it blue.

Finally, you can reset your language in your Language Settings - Login - LingQ

Hope this helps! Let me know if you have any other questions.
