var Combokeys = require("combokeys");
var Mousetrap = new Combokeys(document.documentElement);
// Or, instantiate it for one or more specific elements:
var firstCombokeys = new Combokeys(document.getElementById("first"));

firstCombokeys.bind('4', function() { console.log('4'); });
firstCombokeys.bind("?", function() { console.log('show shortcuts!'); });
