Relevant section taken from src/bin/main.rs:

fn key_to_char(key: Key) -> Option<KeyChar> {
  match key {
    Key::Char('\n') => Some(KeyChar::Press('𐘂')),
    Key::Char(c) => Some(KeyChar::Press(c)),
    Key::Alt(c) => Some(KeyChar::Alt(c)),
    Key::Ctrl(c) => Some(KeyChar::Ctrl(c)),
    Key::Backspace => Some(KeyChar::Press('𐘁')),
    Key::Esc => Some(KeyChar::Press('𐘃')),
    Key::Up => Some(KeyChar::Press('𐙘')),
    Key::Down => Some(KeyChar::Press('𐘞')),
    Key::Left => Some(KeyChar::Press('𐙣')),
    Key::Right => Some(KeyChar::Press('𐙥')),
    _ => None,
  }
}

The special keys backspace, enter, escape, and the arrows, are represented by a single Linear A char. For ease, there are methods to check whether a key press is a backspace, enter, etc, without pasting the Linear A into the code.

Although the arrow keys are supported, please try and support the Vim hjkl if possible!

The Press events are sent as WindowMessage::KeyPress(KeyPress), and the Ctrl events are sent as WindowMessage::CtrlKeyPress(KeyPress). Any keys pressed along with the Alt key are not passed to the windows.
