Controlling an object on a spline

Hello, I am starting a new Project and like to know where to begin with this… What I am doing is having a cube follow the shape of a spline(I am able to set this up already) but what I like to add to it is control buttons to Pause|Stop|Play|Start|FastForward|Rewind|Goto Start|Goto End. where would I start with this are there any key words I could use to find examples?

Thank you
