Retina Macbook Pro power button

When I bought the retina macbook pro, one of the first things I had a gripe about is the new keyboard layout.

Basically the power button is now withint he keyboard, above the delete key.

I was writing a lengthy email, and started to press the delete key, and accidently pressed the power button instead.

This happens many times.

However this time, I wanted to delete and press return to break into a new paragraph.

So since I pressed the power button by mistake, and the return key after, the computer immediately shut down!!!

I wonder if Jonathan Ive actually considered this to happen???

So there a way I can set the default button of the pop up to go to cancel instead of having it on Shut Down?

This way even if I accidently press it, I won't make the mistake of shutting down.

Thanks
