I'm currently programming a math program. It has the features of starting, then displaying math questions until you answered 10 correctly, and then stopping. It works, but the user can only confirm their answer when they press a button (confirm()). This is really annoying. I wanted to make it so that it also activates if the user presses enter while in the entry field.
How to call an event if the user presses enter while their cursor is within the entry field?
