Show what subjects are typing

Hello,

I have a basic task: subjects will answer math problems.

However, they need to be able to actively see what they are typing, and edit it if they want to. (So, for example, when you type an email, you see the characters as you hit keys. If you type the wrong thing, you can correct it.) All the examples I see are such that you hit some keys and they are recorded, but it doesn’t show the keys.

Any advise how to do this in Builder or Coder would be greatly appreciated.

Thanks!

Thanks. Will keep digging.
