Impress Animation Motion Path - Curve

I am trying to use some curve for an animation just for simple rectangle.
What I’m doing is:

  • place a simple rectangle
  • click on the star (custom animations)
  • Add Effect ( + symbol )
  • Category: Motion Paths
    • User Paths: Curve
  • Now I have a cursor to draw curves

and my question is how to end drawing ?

In the documentation it says:

If you select “Curve”, “Polygon”, or “Freeform Line”, the dialog closes and you can draw your own path. If the drawing is finished and not canceled

How to finish the draw?

It’s very simple to use “Freedom line”
