howto enable apple wireless keyboard to send message by pressing cmd-enter

How many key combinations have you tried in order to get the Apple wireless keyboard to send a message instead of inserting a carriage return? 100 as I did? More? Stop trying it because it is not possible without a Cydia tweak. Today I found the answer. Install the free Bluetooth Keyboard Helper from Matthias Ringwald and be happy. It translates the cmd-enter key into a |press 'Send' button" action in the messages.app.
