title: Detect keydown?
body: <p>I would like to detect a keydown event in Rust and then check if a combination of keys is pressed, in order to do further actions based on that.
  So basically support <strong>keyboard shortcuts</strong> in my Rust application.</p>
  
  <p>I've looked at some crates for example <em>ncurses</em> but they did not match my requirements...</p>
