While using a Bluetooth keyboard or Type2Phone makes composing text messages/SMSs easy, tapping the ‘Send’ button at the end is cumbersome.
This tweak translates the Command-Enter key combination on your external keyboard into a “press ‘Send’ button” action in the Messages.app.
No Bluetooth keyboard ? Don’t worry and check out Type2Phone available on Mac AppStore. Requires Type2Phone version >= 1.2
There are no options to configure and no icons are added to the home screen.
