How can I use Enter to send from a bluetooth keyboard? I just purchased a Logitech K760 Wireless keyboard for my Nexus 4.  I have the keyboard paired properly to my phone, but I am unable to send from the keyboard, when sending IMs via Facebook, Skype, etc.

I also have SwiftKey installed, and have tried using both SwiftKey and the default Google Keyboard, and both behave the same way.

Is there a configuration option, or add-on app I can use to control how this works?  My ideal configuration would have ENTER send, and SHIFT+ENTER (or similar) insert a newline.  But I would also be willing to map the send function to one of the F-keys or something else, if that's what I must do.

I am using Android 4.4.2.
This behaviour depends on the application you use, and so, on the way developer(s) programmed their applications.

The application may provide an option to use enter as send, but if it doesn't, then I think you can't do much about this...
