From the developer:
Express yourself in fun, new creative ways using XEmoji for your Mac. Once installed, XEmoji runs in your system menu, providing quick and easy access to all 467 emoji icons. Click on any emoji icons to have it copied to the clipboard. If you are working in an app, XEmoji pastes the copied emoji icon automatically. You can even choose to drag and drop any icons onto your favorite app. It just works.
