How can I "edit points" for freeform in Storyline

I'd love to know how to do this too; can't find any way to edit points. In fact I can't even figure out how to delete a point while you're drawing. If I make a mistake I have to hit escape and I lose all of my work. Oh, I don't have a numpad, don't know if that matters like if the delete key on the numpad is how you delete the last point.

One helpful hint I did figure out though is when you draw free form do not end at a corner; this will leave you with a weird little nub if you use an outline. Instead start drawing in the middle of a line and end there so the weird nub isn't seen (it's covering a line that's already there. I also first built my shape out of primitives then used that as a template to draw my object.
