Drawing with the Scribble line tool is almost the same as drawing with the Freeform line tool, but there is one vital difference. You don’t need to double-click to create an endpoint for your line with the Scribble tool. Also, once you start drawing with the Scribble tool, you can’t release the mouse button until you finish drawing. So, you can’t draw a perfect, straight line as you would do with the Freeform line tool. The point where you release the mouse button will be the endpoint for the drawing.
