Edit Toolbar - Constrain proportions?

I'm trying to implement a simple shape editor for my map using the edit toolbar. I have it working but I'm wondering if there is any way to constrain the proportions of the shape. Like Photoshop, where you hold shift or something similar.

My only thought is that you could connect to the onscale event and constrain them from there... But I can't find any way to do it.

Any thoughts?
