When you place a mouse pointer on an editing point, a crosshair mark will be added to a wedge shape cursor. If a point is dragged in this situation, the target editing point is movable.
A detail adjustment of an editing point can be performed from the point list. Please choose a point to tune finely from a list and change a value by the numeric input field under the list. The numeric value is expressed in units of percentage, the leftmost (or uppermost) of the drawing area is 0, and the rightmost (or bottommost) is 100.
In order to delete an editing point, you place a mouse cursor on the point to delete, and click with the CtrlCommand key pressing, or choose from the list and press Delete or BackSpace key. However, you can't delete when editing points are two or less pieces.
