Arc boost to redirect to WordPress login using Option + Shift + A

content.js

document
  .body
  .addEventListener("keydown", function(event) {
    // Å = option + shift + A
    if (event.key === "Å") {
      redirectToAdmin();
    }
});

function redirectToAdmin() {
  var wpAdmin = location.protocol + '//' + location.hostname + '/wp-admin';
  window.location.replace(wpAdmin);
}

Create a new boost in Arc, and copy/paste this into the content.js file. Set it to run on all websites. You can change the keyboard shortcut to whatever you want.
