Show answer with numbers?

There used to be an add-on that would Show Answer whenever a number was pressed. This was great because you could just double-tap the appropriate number. Does anyone know of a similar add-on, or would it be possible to port it to the current version of Anki? Thanks!

You might be able to do it with this add-on:

Actually I’m not sure its possible with that add-on. I’m writing one myself though and I’ll let you know when it’s done.

Update: add-on is published. Let me know if you have any problems

I could do with some help testing it. Can anyone check if it works on 2.1.41?
Also if anyone has an idea for a better name please do suggest it!
