You can use this tool to delete either individual Bézier points or several Bézier points simultaneously. An individual Bézier point is removed if you click it with the Bézier
cursor. You can remove several points simultaneously if you click the mouse button and drag a selection rectangle while holding down the mouse button. When you release the mouse button, all Bézier points inside the selection rectangle will be deleted. It is unimportant whether the rectangle encloses the points of only one element or several elements.
