 So you just need to move, not a problem. When point action is set to move it lets you move clusters of points by left clicking. By default it is set to brush by radius which just means it will move the points within the red circle of your brush size. While holding left click if you hold shift it will slide your points along the surface of the object and if you hold alt it will move your selection forwards and backwards. Now you can mess with these modifiers down here if you want on your own time but honestly I have never needed to adjust these values. If you set it to infinite x it will control all the points horizontally to what you click and if you set it to infinite y it will do the same thing but vertically. Normally it will only move the points on the same face that you click but if you move brush to infinite depth it will grab all the points that are directly behind the object and if you want to do the same thing but with the same size as your brush radius set it to x, y, z instead. If you only want to grab most of the points behind the direction that the point you clicked is facing then you should try setting mode to infinite z. Hope that helps and as always I hope you have a fantastic day and I'll see you around.
