Support for phone keyboards

[geezuh]

Not so much an issue, as a feature request. I'm trying to use hangups with my phone via ssh to a server, however I cannot navigate tabs without a Ctrl key.

I would like if you could type /n or /p into a chat buffer, and instead of sending that as a message, triggered the next/previous tab function.

I'm a little rusty with programming, but if you could point me to where the message is actually sent, perhaps I could just modify it on my system.

Thanks!

Have a look at the ReturnableEdit class and ConversationWidget._on_return in main.py. You should be able modify those to recognize special commands for the UI.
