What if a letter is still marked “incorrect” even after pressing the correct key?

What does the Require Correct Key option do?

1. During a typing lesson, click the gear icon to open the settings menu. From there, toggle Require Correct Key ON (blue) or OFF (gray).

2. Turning it ON means users must type the correct key to proceed.

3. Turning it OFF allows the lesson to continue even if a key is mistyped.
