Mojibar Is a Keyboard Driven Emoji Search Engine for Mac
Mac: Finding emoji in OS X is just fine, but if you’re looking for something smoother, Mojibar is a menu bar-based emoji app that lets you type emoji quickly and easily.
Once installed, you can download the application using Ctrl + Shift + Space. From there, you can quickly search for emoticons and then insert emoticons into text with unicode or emoticon code.
