A simple JavaScript hotkey helper.
Attach a hotkey like this:
hotkey('input#username', 'ctrl+shift+p', function (event) {
console.log(this.tagName); // 'INPUT'
});If you ommit the selector, the hotkey will be attached to the
<body> element:
hotkey('alt+a', function (event) {
console.log(this.tagName); // 'BODY'
});
