event.key returns the character being pressed
event.preventDefault() prevents the default browser behavior for that shortcut, e.g. ctrl+r usually reloads the page, but event.preventDefault() will turn off that behavior. event.preventDefault() should only be used if you share a shortcut with the same trigger as the browser.
event.ctrlKey / event.altKey / event.shiftKey / event.metaKey all return booleans. They will be true when they are being pressed, otherwise they will be false.
