@Sinyaven’s ConfusionGuesser userscript made me wonder:
Would it be possible to make a script that automatically enters an incorrect answer when you hit “Enter” while the answer field is empty? Maybe just “I don’t know” for meaning reviews, and “知らない” for reading reviews (hopefully the English string wouldn’t ever be marked as “correct” by being close enough to something else).
I know I’ve seen a script that adds a button to do this, but I’m specifically hoping for a convenient keyboard shortcut that doesn’t add anything to the UI. Maybe there could be a setting to either advance to the next review automatically (just press Enter once), or to show the wrong answer and require a second Enter press to continue. I guess the latter would be more useful to me personally, since I use @DaisukeJigen’s Fast Abridged Wrong/Multiple Answer to show me what to type the next time the review comes up.
Edit:
There are also times that I deliberately want to mark something wrong, even though I know what the answer is. Maybe Shift+Enter could be a hard-coded “mark wrong and advance to the next review simultaneously” command, regardless of the default setting/behavior
