The measurement to the left of the indent marker is the left indent and what you want to be 0.86 inches. You’ll notice measurements displaying where the ruler was. Then, click and hold the right mouse button (while still holding down the left button) and move the mouse to the right. Click and hold the left mouse button on the box below the two triangles on the left side of the ruler. Say you want to move the left indent over to 0.86 inches on the ruler.
