Drawing an oval from the centre out?

[JoePrice]

Hi Chaps

In flash using the oval tool you draw ovals from a corner point out.
Does anyone know what the key is to draw an oval from the centre point out?

e.g. in photoshop, hold down alt when drawing an oval selection to draw from the centre out.

Thanks

I really dont think there's a key like that in Flash... Correct me if I'm wrong.
