Way to scrub through timeline via mouse ?

Hi,

Would there be a way to scrub through the clips of my timeline without having to click on the playhead and moving it but just by moving my cursor from the left to the right (without having to click anywhere)?

For instance my cursor here I would like that when I move it to the left or to the right, it scrubs through the video, meaning that on my program monitor the pictures are changing as I go right or left.
