Cannot bind to Control+Enter or Shift+Enter for chat-like behavior in TextArea

[espositocode]

Based on these set of keys, I do not see a binding for Control+Enter or Control+Shift (by itself): https://github.com/Textualize/textual/blob/main/src/textual/keys.py

Is there a technical limitation that prevents these keys from used?

This binding would be particularly useful for TextArea, where the user can distinguish between "submit" and "newline". For example, in most chat apps you can press one of these sequences to generate a newline, where normally pressing enter would immediately send the text.

If I were to build a chat app with Textual, how would I mimic this behavior?

Thanks @davep. So I tried that script to print out the key combinations, and it only prints enter every time.

Just to confirm, this is because the Terminal app doesn't pass along shift or control with enter, and there is basically nothing Textual can do to work around this?

Indeed. Here's kitty, iTerm, wezterm, tabby, Alacritty and Contour, each using showkey, where I'm trying the three key combinations you mention:
