Opening Text Box

Right now my chat window text box started by clicking on it. Im trying to make it happen with a key press, but i cant seem to figure it out. Is there a node or detail im missing to allow this?

What im trying to say is you hit enter, type your message, then hit enter again to send. Im looking for the begining hitting enter

In the event graph you can use “key - enter.” Keep in mind in functions that is not accessible - there you need to define an input action in the project settings and use that.
