Just drag the point to outside of the frame.
Thank you Joanna !!!
It’s strange because the point first modiffy the curve … and disapear when it come outside the frame … but it the right fonction for dellet a point … you are right 
Under Windows, it’s very simple: just left click on the chosen point, then right click, and it is deleted!
