Smooth and sharp points

[Rio]

Hi - sorry if this is a repeat question but I am looking for a way to have a point be half smooth, then half sharp. This function is available on illustrator by holding alt (or something) after putting a point down. Currently in pixelmator I have to drag the handle all the way down to the point to get this effect which is, quite frankly, not the best workflow.

Anyways, please let me know if there is a thread I can refer to already. Just couldnt find it after a quick search.

Thanks
-Rio
