The Feature

I want a feature that InputSender sends events to _shortcut_input and _unhandled_key_input of receivers.

This is a good idea. This might be as simple as adding a few more if blocks to input_sender.gd._send_event(...). I'm not sure if there are any complications between _unhandled_key_input and _unhandled_input existing, or the order they should be called in.
