Fade Out on key press

Hi, I am very new to blueprint and was wondering if there was a way I can press a key then fade to black then open a level and fade back in using blueprint?

I know how to load a level on a key press however I want it to fade to black on the keypress, then fade in when the new level is loaded. I have set up a fade in matinee which I can trigger on a level load but it is the fade-out on a keypress I am getting stuck on.

Thanks in advance
