Unable to detect Shift+Enter

[cs-t1]

I'm currently looking into implementing the multi-line feature using the Shift + Enter keybinding. However it seems the event handling implementation is not able to capture it. Pressing this binding only yields

KeyEvent { code: Enter, modifiers: NONE }

i.e. the SHIFT modifier is not detected.

I remember reading that Shift+Enter is not supported by many terminals and therefore the backend does not support it. I implemented switched the multiline mode btw. via Alt+Enter.
