I have found that if I select multiple words to get a phrase translation, if I press “k” on my keyboard while those words are highlighted, it breaks all keyboard shortcuts until I refresh the page.
You can’t really make a phrase Known unless you saved it as LingQ first. Then, once it is saved as LingQ, you can change its status and make it known. But selecting a phrase and making it known won’t work with shortcut or checkmark.
It shouldn’t, however, break the shortcuts, so I’ll look into it.
Makes sense. I wasn’t really even trying to make it known (since that’s pointless if it wasn’t already a LingQ), I just happened to accidentally hit “k” and notice the bug.
