How to make UMG option menu(control menu) for insert key?

I am making control menu for option menu and I can’t find how to make player insert key to custom it.
What I have tried so far was “text box” but I still can’t figure it out how do I just “press key on keyboard”
and it put on a text box such as “CTRL” “SHIFT” “F1-12” “HOME” “END” etc.

Not sure I understand your question, but if you’re trying to implement Input Binding, check out thisgreat walkthrough.
