Playing the timeline of a movie clip

Hello all. I’m a noob here.

I’m trying to play the timeline forward or backwards by either pressing and dragging left or pressing and dragging right. I can’t figure this out.

I have been using instances of buttons to do this but I don’t want to use buttons I just want to be able to press anywhere on the screen and weather I drag left or right the movie plays, if I stop pressing the movie stops playing on its current frame.

I hope any of you can help me.

Thank You very much.
