-HotKeys.js is an input capture library with some very special features, it is easy to pick up and use, has a reasonable footprint (~3kb) (gzipped: 1.73kb), and has no dependencies. It should not interfere with any JavaScript libraries or frameworks. Official document [demo preview](http://jaywcjlove.github.io/hotkeys). [More examples](https://github.com/jaywcjlove/hotkeys/issues?q=label%3ADemo+).
