`Shift`/`Ctrl` + `Enter` returns `modifiers::NONE`

[Araxeus]

Describe the bug
Ctrl + Enter = modifiers::NONE
Shift + Enter = modifiers::NONE

Alt + Enter = modifiers::ALT

To Reproduce

use crossterm::{event::read, terminal};

fn main() {
	terminal::enable_raw_mode();
	let res = read().unwrap();
	terminal::disable_rawmode();
	println!("{:#?}", res);
}

OS

• Ubuntu 21.10

Terminal/Console

• gnome-terminal

I couldn't test on Mac, but on Windows - all modifiers are returned just fine

Can reproduce on macOS using a few different terminals

Code I used:

use crossterm::{event::read, terminal};

fn main() -> std::io::Result<()> {
    terminal::enable_raw_mode()?;
    let res = read()?;
    terminal::disable_raw_mode()?;
    println!("{:#?}", res);
    Ok(())
}

• iTerm2, Terminal.app
  • Ctrl + Enter = NONE
  • Shift + Enter = NONE
  • Alt + Enter = NONE
• VSCode Integrated Terminal
  • Ctrl + Enter = NONE
  • Shift + Enter = NONE
  • Alt + Enter = ALT

Thanks for reporting the missing keys, those key combinations are likely not implemented yet. I'll leave this issue open such that people can add support for the keys.

Closing in favor of #685.
