Send message on iPhone 4S using PC Bluetooth keyboard? I have successfully paired a Bluetooth keyboard with my iPhone 4S, and it works great for composing messages.

However, I can't find a way to send a message from the Messages app using just the keyboard.
I've tried Enter, Alt+Enter, Ctrl+Enter, and Shift+Enter.

There's a thread on Apple's site that covers the same topic - one of the posts alluded to a "send" button on a full-featured iPhone keyboard.

Does anyone know what extended key code or combination the "official" keyboard is sending?  If not, is there a way to find out?
In Mail for the Mac you can send the current message using Shift + Cmd + D, so maybe try that? 

On my PC keyboard, the Win key sends a Cmd in Mac OS X, yours is probably the same.
