title: Reassign Chrome OS keybindings
body: <p>I'm using Debian installed within a <code>chroot</code> via Crouton, on a Chromebook (OS Version 56.0.2924.110). There are keybindings I need for programs on like Alpine that are also in use by Chrome OS — mostly keybindings involving the CTRL key. The Chrome OS keybindings are numerous — those for CTRL-SHIFT, for instance, are shown in the attached screenshot.</p>
  
  <p>Is there a way to reassign some of these Chrome OS keybindings so that I can use them freely within Debian?</p>
