Set a constant speed when button is held?

I’m not familiar with those games in particular but it seems like you want to press a button and have the player move forward at a higher speed for a given amount of time yes? I just tried using a timeline to push a value to add movement input node like there is on the thirdpersonBP and it seemed to work. I set the timeline to a value of 1 and a duration of 3 seconds.
