I think f-r-t are not very intuitive and easy keys for answering flashcards.
Hmm, I am not sure if I agree.
s= show answer
t= Took a while to recall
but i think it’s not FAST as four keys close together in one line like 1234 and would be better to be customizable.
@mrez Ok I see. So your feature request is not asking to replace the default keys, but to make them customizable in keyboard shortcuts.
