Mojito

Mojito とは？

Autocomplete :emoji: everywhere on macOS. Type a colon and search any emoji, symbol, or shortcode in seconds — in TextEdit, iMessage, Terminal, anywhere. Slack and a few other apps have this — type :heart: and you get ❤️. It makes finding emoji easy. I wanted it everywhere on my Mac, so I built Mojito. It works just like you'd expect, and it's smart enough to ignore apps and sites that already support it. And it's free, open-source donationware.
