Normally, I don’t use my mouse when doing reviews, but I am forced to for 10K sentence reviews since the enter doesn’t flip over the card and isn’t a shortcut for “know.”
It would be nice if it was a shortcut so one didn’t have to keep going back to the mouse.
So basically you’re typing the answers out and suddenly u get a sentence card with Know/Don’t know, and you have to go on and flip the card?
There’s a setting for that (the flip card hotkey). Correct and Wrong are the hotkeys to make flipped cards correct or wrong.
I hope I understood you correctly in what you’re looking for o:
You can find it on settings.
Ah awesome thank you!
