Concerning shape keys

How would I mirror a shape key? For example, I have a blink shape key for a characters left eye, how would I go and mirror the shape key for his right with out doing it over again?

Thanks in advance!

Same as in your duplicate thread.
Here’s a very simple demo http://www.screencast.com/users/blenderwho/folders/Jing/media/51f00294-1d14-4851-ac6f-bd5b8a3299f8

Nifty! Used to have to model both sides in older versions of Max.
