Ok, Google Now... (Post your tips here)

I actually don't have any tips but really wanted to post this because there's a feature from the Droid line which I'm hoping has an equivalent on the Moto X.

For those of you with a Droid with touchless controls, you can say "Ok Google Now, Call my Droid" when you can't find it and the phone will play an alert tone and flash until you touch the screen.

Does anyone know a Moto X equivalent?
